Subject RE: Hadoop YARN Map Reduce Job failing with a Null Pointer Exception.
Date Sat, 06 Jun 2015 07:07:21 GMT
Hi,Your error stack looks simmilar to the this issue in jira: https://issues.apache.org/jira/browse/MAPREDUCE-5703Maybe
worth reading the link as it seemed to be resolved (but not as a patch, more as a development
issue)
With Regards,Yves
