DistCp fails when invoked by Oozie
----------------------------------
Key: MAPREDUCE-4004
URL: https://issues.apache.org/jira/browse/MAPREDUCE-4004
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: distcp
Affects Versions: 0.23.1
Reporter: Mithun Radhakrishnan
Assignee: Mithun Radhakrishnan
When DistCp is invoked through a proxy-user (e.g. through Oozie), the
delegation-token-store isn't picked up by DistCp correctly. One sees failures
such as:
ERROR [main] org.apache.hadoop.tools.DistCp: Couldn't complete DistCp
operation:

at org.apache.hadoop.mapred.YarnChild.main(YarnChild.java:142)
Looking over the DistCp code, one sees that HADOOP_TOKEN_FILE_LOCATION isn't
being copied to mapreduce.job.credentials.binary, in the job-conf. I'll post a
patch for this shortly.
