@atul kumar

Are you running Mapreduce in local mode?

Seems like either you don't have commons-httpclient-<version>.jar file in class path or probably multiple versions of same jar conflicting. Please cross check.

commons-httpclient is already added with only one version. Can you guide me how to run Mapreduce in HDFS mode? I am using Java in eclipse.

Thanks!

How can I know that if it is running in local mode or HDFS mode?

@atul kumar

If you run the job it will give you job_id. If the job_id is something like job_<12312324233242> then assume that oyur job is running in HDFS mode. If the job_id is job_local** then its local mode.

How are you running this map reduce job? can you share the command or the scenario.?

Re: ERROR util.ProcfsBasedProcessTree: java.io.IOException: in MapReduce program

atul_net — Sun, 29 May 2016 02:34:10 GMT

Yes it is in local mode. My job Id is: job_local295133331_0001. What should I do to resolve this issue?

Hi @atul kumar,

Looks like jar wasn't imported into the project while creating, can you please follow below doc and see if that resolve your issue?

Thanks

@Jitendra Yadav for addressing this issue. I created a new project and imported all jars from Hadoop/common/lib directory. Earlier I have just set the path to hadoop directory jars which was not working. This issue seems resolved for now.
