java - Error while running Mapreduce(yarn)from windows eclipse

Question

I am running a WordCount program from my eclipse. I tried with Hadoop1.x it is running fine. Facing issue while running on hadoop2.x

i tried 1)added all xml into my classpath. 2)also tried conf.set(), setting xml properties in conf object.

Also in logs it says :-No logs available for container container_1394042163908_0573_01_000001

  Application application_1394042163908_0573 failed 2 times due to AM Container for      appattempt_1394042163908_0573_000002 exited with exitCode: 1 due to: Exception from container-launch:

Answer 1

I have figured out the issue, there is a jira for it:https://issues.apache.org/jira/browse/MAPREDUCE-5655

I just added YARNRunner.java & MRApps.java to my project . It also reqires to add the following property to mapred-site.xml on the windows box, so that the job launcher knows, that the job runner will be a linux:

<property>
<name>mapred.remote.os</name>
<value>Linux</value>
<description>Remote MapReduce framework's OS, can be either Linux or Windows</description>
</property>

And MapReduce is running fine now.

Also Copy org.apache.hadoop.util.Shell.java into your project.

You can comment out the below line,to remove the winutils.exe Error.
throw new IOException("Could not locate executable " + fullExeName + " in the Hadoop binaries.");
