I am very new to hadoop. I need to install it and play around with samples.
SO i referred this tutorial . I have installed Sandbox given in that tutorial. I need to configure ECLIPSE in windows mentioning VM location as specified in the image below, which is given in the tutorial.
I have installed eclipse europa and hadoop plugin.
Then in Map/Reduce Locations i gave VM Ip for host name, Linux user name in UserName and 9001 in Map/Reduce port and 9000 in DFS port.
In Advanced Tab I have set value to the mapred.system.dir as /hadoop/mapred/system
and there is no hadoop.job.ugi to give username.
After i click ok, I couldn't get HDFS file system under my DFS locations in ECLIPSE.
Please help me on this
I also got the same problem. The problem here is not related to hadoop configuration but eclipse. To fix this, go to "\workspace\.metadata\.plugins\org.apache.hadoop.eclipse\locations". Here open the XML file and just add the property "hadoop.job.ugi" with value "hadoop-user,ABC" and then restart your eclipse. It worked for me.
I tried by giving just one value i.e. without ABC but it dint work and I dont know the significance of this comma separated value but since I have just started the tutorial I hope to get this answer soon :)
I too ran into the same issue. I installed RedHad cgywin (openssh and openssl packages) and updated the "Path" environment variable with a path to cgywin/bin (c:\rhcygwin\bin). Then my Eclipse DFS location was able to connect to Hadoop on the Virtual Machine. Once that was successful I saw the option "hadoop.job.ugi".
http://v-lad.org/Tutorials/Hadoop/00%20-%20Intro.html describes installing cgywin.
Note: I am running the Hadoop VM on Windows Vista.
I spawned Eclipse from within Cygwin and it worked fine for me (i.e. I could see the "hadoop.job.ugi" parameter). Also, I didn't make any changes to my PATH environment variable.

I am new to Go and installed latest windows version of Go:

That GOPATH-C:\Users\avnee\go does not exist in my machine. Even when I set it to different path, it does not work. I want to run simple "hello world" program in eclipse.
wanted to set variables. Ideally I expect to see below variables as gocode, guru and godef in my machine and then I can set it. Referred the official url: "https://go.dev/doc/gopath_code#GOPATH" but does not help.

I used the host and port in the return statement and did as explained below

Does anyone know what else I can try because I am still getting a network problem message?
Your help will be appreciated
Proxy Network problem message:
I have changed the active provider to Manual and retried again, then it worked.
I installed an old version and it's worked well.
this is the link for the old version:

You can download a zip file of the Eclipse package you want and explode it in your filesystem where you want it,
Here is link for Eclipse package for windows:

For me, I had similar issues to this that related to my office network and their use of a security tool called Netskope which needed its root-certificate into the jvm that would be used by the Eclipse installer. I elaborated on my workaround steps in this other thread:

for the past several days I've been experiencing this error, while publishing to either JBoss EAP 6.3 or Wildfly 8.2 from Eclipse.
Error renaming D:\Servers\wildfly-8.2.0.Final\standalone\tmp\tmp9064011157118650757.jar
to D:\Servers\wildfly-8.2.0.Final\standalone\deployments\BusinessService.war\WEB-INF\lib\spring-web-4.2.3.RELEASE.jar.
This may be caused by incorrect file permissions, or your server's temporary deploy
directory may be on a different filesystem than the final destination. You may adjust
these settings in the server editor.
The problem occurs when I "Add and Remove..." projects from the server, then try to publish them, so the server can start.
I've experienced this issue on two different machines (home (Wildfly) and work (JBoss EAP)).
I'm using:
Windows 7 / 10
Eclipse Mars / Luna
JBoss Tools plugin 4.3 / 4.2
JDK 1.8.0.66 / 1.8.0.65
Maven
Building with maven from Eclipse and from the command line makes no difference. The server is configured to deploy projects as compressed archives. On both machines my user has administrator rights and has full rights on the server directory.
So far I've tried:
recreating the server multiple times with different configurations
using a newly created workspace
reinstalling JBoss Tools
reinstalling Eclipse
using different JDK versions
I'm really at a loss here and I don't know how to proceed in resolving this issue. Please help.
If you are using Windows, the path could get too long and can cause this error. A simple fix is to move WildFly closer to the root.
I had the same problem and solved it like this:
First of all, stop Server (Servers->WildFly(rigth click)->Stop), than clean. So you can run server again.
I had this problem several times in my new windows 10 machine that my employer gave me. Since I did not have admin rights it was a hectic process to troubleshoot this issue. Simple fix would be moving JBOSS_HOME closer to root. However, you need to do a proper restart of your eclipse. I rather recommend a complete restart of your computer because after all you are going to change JBOSS_HOME in windows environmental variables.
This is related to permissions issue on wildfly folder. Allow full control to the wildfly folder.
https://issues.jboss.org/browse/JBIDE-18697
I have moved the wildfly home to reduce the overall path length, and also removed any non-alphanumeric characters from the folder name (like "-" and "." ) . This worked for me, everything else (removing tmp, deployment, rebooting wildfly, rebooting eclipse, rebooting computer) failed.
I also suspect that the issue was stemming from running Wildfly from a ConEmu and/or git bash shell. Running from a plain CMD shell seems more robust.
I also got stuck with the same problem. I tried the below steps and it worked:
Clear the deployments and tmp folder in standalone folder in wildfly folder.
Delete the server and again add the server
Make a build of the project and start the server after successful build.
This is a terribly annoying error that either the Eclipse team or Redhat need to fix.
The solution is to close Eclipse, right click on the icon -> Run As Administrator. This solved it for me.
I have the following question: I have imported in eclipse the tika-server subdirectory of the tika-trunk main repository and managed to import it to eclipse and I am able to start the "Apache Tika 1.7-SNAPSHOT server" on the machine I run eclipse (localhost). My problem is that I can only access Tika from this machine (localhost).
I know how to solve this problem when I start the Tika server from my command line (see post Stopping a Tika server properly ), but I do not know how I can pass "-host 0.0.0.0" in order to instruct eclipse to do the same. I know that this might be solved through the "Run Configurations" eclipse menu but it is not intuitive to me how I can accomplish that. Thank you in advance !
First up, you need to open the Tika Server Cli class in eclipse. Then, do Run As followed by Run Configuration, as shown here:
Now, in the configuration for the Tika Server CLI, in the program arguments box, enter the arguments you want to give to Tika, eg --port 9876 as shown here
Finally, hit Run and the Tika Server will start with the alternate port you've givne
I think the only solution so far I found is to edit "TikaServerCli.java" and switch "public static final String DEFAULT_HOST" from "localhost" to "0.0.0.0". Then you can start the server in a way that can be accessed by everyone and not only by localhost.
I've downloaded hadoop from Yahoo tutorial, started linux VM with hadoop and in eclipse created new DFS location (entered IP of my VM, Map/Reduce master port 9001, DFS port 9000.
But in the node I got the error "Error:null."
What I'm doing wrong?
I'm using Eclipse Europe 3.3.1 and Hadoop 0.18.0.
Thanks for helping.
You should check the additional properties that you are able to configure. I was also getting this problem but the actual problem was that hadoop.job.ugi property was not available to be setup.To fix this, go to "\workspace\.metadata\.plugins\org.apache.hadoop.eclipse\locations". Here open the XML file and just add the property "hadoop.job.ugi" with value "hadoop-user,ABC" and then restart your eclipse. It worked for me.
I've configured properly eclipse when had installed it in my VM where hadoop was. But due to incompatible new versions of eclipse and eclipse hadoop plugin I refused to use it, because seems to me that using this plugin doesn't have any good benefits.
I was facing the same problem, i thinks the problem because there is no folder or files in the HDFS,i solved with these steps:
hadoop dfs -mkdir /name of folder
hadoop fs -ls /
