> 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.
