My os is OS X Yosemite. The hadoop version is 2.6.0 and eclipse is luna.

Anyone has idea about this problem?

[jainmanoj]

I also faced this issue.
I have setup with hadoop 2.6.0 (Installed remotely on Linux system)
I am setting up eclipse plugin on windows remotely

How to fix

Change the hadoop version in libraries.properties with
hadoop.version=2.6.0

Add the htrace-core-3.0.4.jar
add following line in src/contrib/eclipse-plugin/build.xml

rebuild
and deploy plugin

Hope it will solve your issue

[lmcl90]

Thanks, but it doesn't work!

I firstly changed the hadoop version in ${hadoop2x-eclipse-plugin}/ivy/libraries.properties to 2.6.0 and in ${hadoop2x-eclipse-plugin}/src/contrib/eclipse-plugin/build.xml , I added a new line <copy file="${hadoop.home}/share/hadoop/common/lib/htrace-core-3.0.4.jar" todir="${build.dir}/lib" verbose="true"/> and an element lib/htrace-core.3.0.4.jar in the value of node: <attribute name="Bundle-ClassPath" .

Rebuild and deploy again.

Is this right?

[jainmanoj]

Please add the manifest attribute to include
........
lib/netty-${netty.version}.jar,
.....

lib/htrace-core-3.0.4.jar"/>

For me it works fine.

Thanks
Manoj

I tried, but it still didn't work... But thanks a lot!

[jainmanoj]

Hi Ming,

Did your compilation successful. Please verify if your manifest file is
correct after compilation.

Now deploy the plugin in eclipse ( %ECLIPSE_HOME%\plugin)

Restart eclipse

eclipse -clean -consolelog -debug

If it doesn't work, I sent send you my compiled binaries (It is for windows
platform for Hadoop 2.6.0)

Thanks
Manoj

Hi Manoj,

Ant said the compilation was successful, although there was a warning [javac] /Users/lim/Documents/github/hadoop2x-eclipse-plugin/src/contrib/eclipse-plugin/build.xml:76: warning: 'includeantruntime' was not set, defaulting to build.sysclasspath=last; set to false for repeatable builds .

I extracted all files from the complied binaries and saw the classpath in manifest file contained “lib/htrace-core.3.0.4.jar” and there was a htrace-core.3.0.4.jar file under the lib directory. The jar file should be correct.

After redeployed and started eclipse again to connect to hdfs, same error occurred.

I have tried what you said, but it still did not work. Please send me your binaries and I will try with it.

Thank you very much for your help!

Hi Manoj,

The project had already updated to hadoop 2.6.0 and I used the plugin released by the owner of
the project. That worked fine for me. Sorry forgot to tell you that.

Thanks so much!

Hi Guys,
I want to build hadoop-eclipse-plugin-2.7.1.jar, but failed.
The platform is Ubuntu 14.04 x86_64. The version of hadoop is 2.7.1.
I had modified the "build.xml" about "htrace-core-3.1.0-incubating.jar" and I doubt there is something wrong with "htrace-core-3.1.0-incubating.jar".

The error info as follows:
An internal error occurred during: "Connecting to DFS MyHadoop".org/apache/htrace/SamplerBuilder

Please any one help me Thanks in advance.

same issue as "emailfeifan" however for hadoop 2.7.2 and Ubuntu 15.04. "htrace-core-3.1.0-incubating.jar" reflects in manifest.mf. "htrace-core-3.1.0-incubating.jar" is packaged inside lib of the plugin.

Can not figure out why...perhaps htrace-core-3.1.0-incubating.jar does not work with hadoop 2.7.2 yet??

hadoop-eclipse-plugin-2.6.0.jar works for me with hadoop 2.7.2 (as mentioned in #30).
