Distcp should not use mapred.system.dir
---------------------------------------
Key: MAPREDUCE-940
URL: https://issues.apache.org/jira/browse/MAPREDUCE-940
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: distcp
Reporter: Ravi Gummadi
Distcp uses mapred.system.dir to create files like _distcp_src_files,
_distcp_dst_files, etc. Since MAPREDUCE-181 is removing exposing of
mapred.stystem.dir, distcp needs to use something like homeDir/.staging/
instead of mapred.system.dir. Please see the patch of MAPREDUCE-181 for more
details.
