Subject Re: [jira] [Created] (MAPREDUCE-5380) Invalid mapred command should return non-zero exit code
Date Fri, 12 Jul 2013 06:21:42 GMT
Hey Team,
Same with me, I have also joined this group recently.It would be great if
someone could help me getting started. I have some experience of working in
java. I have recently learning Map-Reduce Framework.And want to gain some
more detail knowledge.If any one can give me some small assignment to start
and guide me for completing the same that would be of great help.

Thanks,
Sagar
