Error from Zookeper 3.4.6 version - apache-zookeeper

I downloaded zookeeper-3.4.6.tar.gz and while executing zkServer.sh start , I am getting below error.I did google but couldn't find a solution, Please let me kno if you see similar issues.
CLASSPATH=/home/spanda20/zookeeper/bin/../src/java/lib/*.jar:/home/spanda20/zookeeper/bin/../conf:
zkServer.sh: 81: /home/spanda20/zookeeper/bin/zkEnv.sh: Syntax error: "(" unexpected (expecting "fi")

Finally I am able to see storm UI and its running.
Below changes I did in the .bashrc file. Please make sure that You add bin path in the PATH VARIABLE.
I did add the below variables in the .bashrc file.
export JAVA_HOME =JDK Path
export ZOOKEPER_HOME =Zookeper install path
Then add them in the variable path.
PATH= $PATH:$JAVA_HOME/bin:$ZOOKEPER_HOME/bin
Thanks

I'm using zookeeper version 3.4.9 on ubuntu 14.04 and installed openjdk 7. I have added below lines to ~/.bashrc
export JAVA_HOME="/usr/lib/jvm/java-7-openjdk-amd64"
export ZOOKEEPER_HOME ="/path/to/zookeeper"
PATH=$PATH:$JAVA_HOME/bin:$ZOOKEEPER_HOME/bin.
First I ran sh /path-to-zookeeper/bin/zkServer.sh start but didn't not work I got the same error.
I ran it with sudo /bin/bash /path-to-zookeeper/bin/zkServer.sh start it worked.

./zkServer.sh start
This should work.
Edit /etc/environment, and paste the following:
JAVA_HOME="/usr/lib/jvm/java-8-openjdk-amd64/jre"
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:$JAVA_HOME/bin"
modify the JAVA_HOME as per your local Java version.

How to fix diesel_cli link libpq.lib error with Postgres tools installed in Docker?

I'm trying (for hours now) to install the cargo crate diesel_cli for postgres. However, every time I run the recommended cargo command:
cargo install diesel_cli --no-default-features --features postgres
I wait a few minutes just to see the same build fail with this message:
note: LINK : fatal error LNK1181: cannot open input file 'libpq.lib'
error: aborting due to previous error
error: failed to compile `diesel_cli v1.4.1`, intermediate artifacts can be found at `C:\Users\<user name here>\AppData\Local\Temp\cargo-installUU2DtT`
Caused by:
could not compile `diesel_cli`.
I'm running postgres in a docker container and have the binaries on my C:\pgsql with the lib and bin directories both on the PATH so I can't figure out why it's not linking. What else could be required they didn't mention in the docs?
In my case the installation was successful but when I tried to run it this error occured.
maybe this would work for others who have the same problem:
open PowerShell
type in setx PQ_LIB_DIR "C:\Program Files\PostgreSQL\13\lib" (or any other path to your PostgreSQL lib)
restart your PC
run again
I had the same issue with WSL, if you're on Linux probably you could find PostgreSQL lib location and add it to your environment variables.
Update:
The answer below is a work around for older versions. Please check the possibility to execute cargo clean first
Original Version
Adding the folder to the PATH variable didn't help, at least in my case, as by some reason it is not used in the /LIBPATH parameter passed to link.exe.
In my case it was C:\Users\<username>\.rustup\toolchains\stable-x86_64-pc-windows-msvc\lib\rustlib\x86_64-pc-windows-msvc\lib
You can see it in the beginning of the error message.
Copy libpq.lib in there and it will be used from there.
After installation diesel would require some other assemblies. Copy libcrypto-1_1-x64.dll, libiconv-2.dll and libssl-1_1-x64.dll into the folder showed after where diesel command execution
I had the same error on Ubuntu and for me the following install fixed the issue:
sudo apt install libpq-dev
No need to move files around, just add C:\Program Files\PostgreSQL\14\lib and C:\Program Files\PostgreSQL\14\bin to your PATH. Installing and running diesel should have no problems.
Note: your paths may be different, and remember to close/reopen your terminal so the PATH variable is updated.
(Tested on Windows 10)
To give clear steps for windows:
Add C:\Users<username>.rustup\toolchains\stable-x86_64-pc-windows-msvc\lib\rustlib\x86_64-pc-windows-msvc\lib in the path in environment variables
Copy libpq.lib that is in C:\Program Files\PostgreSQL\14\lib (obviously this is with version 14) and paste it in C:\Users<username>.rustup\toolchains\stable-x86_64-pc-windows-msvc\lib\rustlib\x86_64-pc-windows-msvc\lib
If you've attempted to cargo build (or anything that runs the build scripts for libpq rust crate) when your environment was invalid, then you need to do a cargo clean after fixing your environment otherwise you'll still get the libpq.lib not found error even when it's in your PATH. The other answers where you copy the file into another directory are just hacks
You can instead add the path to .../lib to the compilers' library search paths, using RUSTFLAGS environment variable. It works both for installing diesel_cli and for building your projects.
RUSTFLAGS='-L /usr/local/pgsql/lib' cargo build
On Windows with EDB installer, the path contains a space, so use CARGO_ENCODED_RUSTFLAGS instead. For PowerShell:
$env:CARGO_ENCODED_RUSTFLAGS = "-L`u{1f}C:\Program Files\PostgreSQL\14\lib"

I am trying to set up Kafka in my local mac

I have unzipped the kafka_2.12-2.5.0 version and started zookeeper and when I am trying to start kafka using the command
"bin/zookeeper-server-start.sh config/zookeeper.properties" i am getting the following eror:
/Users/manig/Desktop/kafka_2.12-2.5.0/bin/kafka-run-class.sh: line 317: /Library/Java/JavaVirtualMachines/jdk1.8.0_191.jdk/Contents/Home#/bin/java: No such file or directory

I tried adding double quotes around the JAVA term like this: "$JAVA" and also changing the classpath to cygpath -wp $CLASSPATH but still getting the same above error
can someone please help me with this..!
Try to set your Java ClassPath properly using the below commands. It was not able to recognize you JDK.
export JAVA_HOME="$(/usr/libexec/java_home)"
or
export JAVA_HOME=`/usr/libexec/java_home`
cygpath is for Cygwin, not Mac.
If you want to install on a Mac, just use brew install kafka
Or use Docker

Sipp with pcap installation on windows

I am trying to install sipp with pcap-replay on winows7.
I have installed cygwnin, libncurse, and winpcap. I was trying to patch cygwin with IPv6 using the URL http://cygwin.win6.jp/cygwin-ipv6/, but it couldn't get the setup.ini file.
So I copied to local directory and upgrade, but it said no new updates.
And if I try to complie sipp. it gives error
$ ./configure.ac --with-pcap
./configure.ac: line 3: syntax error near unexpected token [SIPp],'
./configure.ac: line 3:AC_INIT([SIPp], [3.3], [sipp-users#lists.sourceforge.net], [sipp])'
Could anyone help me in getting sipp be installed on windows?
I download sipp.3.3.990 it has ./configure and was able to install on Linux.
But now on windows it still fails saying ncurse is not present. But I have downloaded it.
How do I troubleshoot it from here?
You can follow below steps to generate configure from configure.ac.
$> autoreconf -i
Now, you will see a configure file created at the same location.
To run the above command, following packages are required: automake,ncurses-devel,libncurses,M4 and autoconf.
if any of the above packages are missing run the cygwin setup file again and select the packages on the package selection screen and click install.

pg_ctl: error while loading shared libraries: libpq.so.5

I'm trying to get postgres server status with:
sudo /etc/init.d/postgres status -u postgres
But getting following error:
/home/alex/olddisk/usr/local/pgsql/bin/pg_ctl: error while loading shared libraries: libpq.so.5: cannot open shared object file: No such file or directory
I added:
export LD_LIBRARY_PATH=""
export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/usr/local/lib/"
export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/home/alex/olddisk/usr/local/pgsql/lib/"
to my .bashrc, but it didn't help.
Thank you.
I ran into this error when I built postgresql from source using the --prefix flag. Building from source installs the necessary shared libs to the libs folder under the prefix directory you specified, instead of the usual place installations put shared libs. To solve the problem I just added the [prefix].libs folder to the LD_LIBRARY_PATH environment variable. For example, after building postgres using --prefix /mike/sandbox/postgres, the below command solved the issue:
export LD_LIBRARY_PATH=/mike/sandbox/postgres/lib:$LD_LIBRARY_PATH
I think this issue is duplicated, I faced the same problem and posted a solution here.
try this:
1: Know the path of "libpq.so.5"
find / -name libpq.so.5
Output example: "/usr/pgsql-9.4/lib/libpq.so.5" If found nothing, check if you have already installed the suitable postgresql-libs for your postgresql version and your OS platform
2: Symbolic link that library in a "well known" library path like "/usr/lib":
ln -s /usr/pgsql-9.4/lib/libpq.so.5 /usr/lib/libpq.so.5
Attention: If your platform is 64 bit, you MUST also symbolic link to 64 bit libraries path:
ln -s /usr/pgsql-9.4/lib/libpq.so.5 /usr/lib64/libpq.so.5
3: Be happy !
Please ensure you have 'postgresql94' package installed as well (in addition to postgresql94-server, postgresql94-lib, postgresql94-devel and whatever other PG related package you already have). These libraries get installed along with that package.
Some ideas:
Your modified ~/.bashrc only takes effect when you start a new (interactive) shell. Though catching up on that will not help you because:
/etc/sudoers, your configuration file of sudo, probably specifies env_reset. This means, that /etc/init.d/postgres will not see the content of $LD_LIBRARY_PATH of your shell.
Insert debug statements in /etc/init.d/postgres to verify what I told you: echo "LDPATH: $LD_LIBRARY_PATH" >&2
Check /etc/init.d/postgres. Probably you will have to insert the third one of your export statements near the start of this script. Or you will have to update an existing export LD_LIBRARY_PATH= statement.
Have you installed the necessary libraries?
If you are using ubuntu try:
sudo apt-get install libpq libpq-dev

openjdk-1.7.0_55 on ubuntu: Could not load the property file 'output_xml.properties' for output method 'xml'

On openjdk-1.7.0_55 on ubuntu I am getting exception:
com.sun.org.apache.xml.internal.serializer.utils.WrappedRuntimeException: Could not load the property file 'output_xml.properties' for output method 'xml'
Can this be classpath issue?
I can find "output_xml.properties" in /usr/lib/jvm/java-1.7.0-openjdk-amd64/jre/lib/resources.jar.
Any help is appreciated.
Thanks!
The issue might have been caused by a recent Java update and incomplete services restart per this page.
you need to include the xalan JARs in the ../jre/lib/endorsed folder
from http://xml.apache.org/xalan-j/faq.html#jdk14:
Place the xalan.jar, serializer.jar, xercesImpl.jar and xml-apis.jar
in the \lib\endorsed directory, where is where
the runtime software is installed.
Try ensuring that your system is consistently using the same Java version - sometimes these get out of sync.
First do echo $JAVA_HOME and verify that it points to /usr/lib/jvm/java-1.7.0-openjdk-amd64/.
Now run sudo update-alternatives --config java and select the correct number for /usr/lib/jvm/java-7-openjdk-amd64/jre/bin/java
Now do the same for javac: sudo update-alternatives --config javac.
If you're using SYS V init scripts and running in a container such a Tomcat, DON'T start the script directly with:
sudo /etc/init.d/tomcat7 start
That will start it without a clean environment.
Instead, use the service command:
sudo /sbin/service tomcat7 start
