> DistCp v1 currently copies files to a tmp location and then renames that to the specified
destination.  This can cause performance issues on filesystems such as S3.  A -skiptmp flag
will be added to bypass this step and copy directly to the destination.  This feature mirrors
a similar one added to HBase ExportSnapshot [HBASE-11119|https://issues.apache.org/jira/browse/HBASE-11119]
