> 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:

> 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.
