I am trying to start kafka-connect using:
connect-distributed /etc/schema-registry/connect-avro-distributed.properties
, but then I get:

The schema url is presented. I've also tried to start it using:
connect-distributed /etc/kafka/connect-distributed.properties
, which uses the json format, but I get the same error.
Any ideas ?
Please start Schema registry service pointing to the right property file. It should work.
I am trying to tun the latest version of Kafka (kafka_2.11-0.9.0.0) on windows. I did change the log and tmp directories in all the config files and when I try to start the zookeeper server and getting the below error:
[2015-12-20 18:43:10,826] ERROR Unexpected exception, exiting

C:kafka-runtime is the directory that I have created C:\kafka-runtime, here I can see that "\" is being removed.
I installed Zookeeper and tried to install Kafka0.8.0 on Cloudera5.4.4. It successfully deployed, but when I ran it, it failed. The error log as following:
[Errno 2] No such file or directory: '/var/log/kafka/server.log'
I really have no any idea.
Thanks in advance!
I met this problem before, the default maximum memory of brokers were set to 0MB by Cloudera(it seems a bug of Cloudeara), it caused Kafka could not get run, and the parameter fetch.message.max.bytes also was set to low by default. Check the stderr installation log, search keyword ERROR, otherwise the log too messy to check. You would find the root error message. The message above [Errno 2] No such file or directory: '/var/log/kafka/server.log' is not the root exception.
I am trying out the nxlog kafka out module from below
Link
I get the below error message
ERROR Failed to load module from /usr/local/libexec/nxlog/modules/output/om_kafka.so, /usr/local/libexec/nxlog/modules/output/om_kafka.so: undefined symbol: rd_kafka_topic_new;DSO load failed
ERROR module 'outKafka' is not declared at /usr/local/etc/nxlog/nxlog.conf:65
ERROR route tcproute is not functional without output modules, ignored at /usr/local/etc/nxlog/nxlog.conf:65
I am using :
Nxlog Version - nxlog-ce-2.8.1248
Kafka Version - kafka_2.9.2-0.8.1.1
Latest librdkafka
Also the example programe of librdkafka (rdkafka) for both producer and consumer runs fine so I guess the environment is set correct for librdkafka ,
but am unable to determine what's causing this problem.
The problem is that om_kafka.so is not linked with librdkafka.
You will need this in Makefile.am:
om_kafka_la_LIBADD = $(LIBRDKAFKA) $(LIBNX)
The value of $(LIBRDKAFKA) should be properly set ,normally this is done in configure.in. Otherwise you could just use the full path to the library (.so or .la or .a )
To install kafka , I downloaded the kafka tar folder. To start the server I tried this command :
bin/zookeeper-server-start.sh config/zookeeper.properties
The following error occured on entering the above command:
INFO Reading configuration from: config/zookeeper.properties (org.apache.zookeeper.server.quorum.QuorumPeerConfig)

Is it that I need to setup zookeeper separately? How could I resolve this?
For Windows:
Go to kafka_2.11-2.0.0\bin\windows folder
Then run zookeeper-server-start.bat ../../config/zookeeper.properties
This is basically because of this
java.lang.IllegalArgumentException: config/zookeeper.properties file is missing
it would be really useful if you could share what exactly have you done so far. Also check if the same file exists at the said location and you are running the command from the correct location .. it is supposed to be run from your $KAFKA_HOME folder (where you've extracted the tar file)
I too faced the same issue when I installed kafka from Brew on Macbook
This is happening because the zookeeper.properties file is not in config of bin.
Follow these step.
Enter the command---> cd /usr/local/Cellar/kafka/2.3.0
Enter the command ---->cd libex
Now enter the command--->zookeeper-server-start config/zookeeper.properties
You will get the INFO binding to port 0.0.0.0/0.0.0.0:2181 (org.apache.zookeeper.server.NIOServerCnxnFactory) Message.
Earlier I was getting this error:
$ zookeeper-server-start config/zookeeper.properties

I saw when you run the above command it doesn't take config file. So if you Put complete path like c:\Kafka\config\zookeeper.properties... this works.
I faced the exact same error, and after a while I realized that the reason for the error was, I wasn't able to find the zookeeper.properties file, and that was because the path wasn't correct, I installed kafka through brew so the config folder was created inside libexec, so find where the config directory is and check for zookeeper.properties inside it and give that path.
Had the same issue.
I was following this guide and step 2 mentions to run this command:
bin/zookeeper-server-start.sh config/zookeeper.properties
I had 2 problems, that first was that I wasn't inside the root directory of the file you untar and the second was that I didn't copy the complete command. Make sure both of them are correct and try again.
Just make sure that whether /config folder exist or not.
Try to type properties directly. e.g. zookeeper-server-start zookeeper.properties
I installed it with homebrew, it works.
This happens because bin/windows is added to the path but kafka/config is not.
Just navigate to your kafka folder and then try to run.
I am adding screenshot if it can help.
Before
After
You can use Powershell as an alternative to CMD.
Consider myKafka is your kafka home directory, Extract your kafka tar file here.
Extracted folder(KafkaDir) will be having ./bin,/config, etc. internal folders.
Now, open Powershell prompt, go to myKafka folder.
Run below command:
.\kafkaDir\bin\windows\zookeeper-server-start.bat
.\kafkaDir\config\zookeeper.properties
Zookeeper will get start.
You need to fix the absolute path to:
$KAFKA_HOME/config/zookeeper.properties
For me I used:
$KAFKA_HOME = /usr/local/kafka
In \bin\windows\kafka-run-class.bat add the file content
rem Classpath addition for release
for %%i in ("%BASE_DIR%\libs\*") do (
call :concat "%%i"
)
// Section to Add
rem Classpath addition for LSB style path
if exist %BASE_DIR%\share\java\kafka\* (
call :concat %BASE_DIR%\share\java\kafka\*
)
**
// Above Section to Add
rem Classpath addition for core
for %%i in ("%BASE_DIR%\core\build\libs\kafka_%SCALA_BINARY_VERSION%*.jar") do (
call :concat "%%i"
Have to run in from Kafka home directory, but you are running from the bin.
