[jira] [Created] (HDFS-7312) Update DistCp v1 to optionally not use tmp location

Joseph Prosser created HDFS-7312:
------------------------------------

             Summary: Update DistCp v1 to optionally not use tmp location
                 Key: HDFS-7312
                 URL: https://issues.apache.org/jira/browse/HDFS-7312
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: tools
    Affects Versions: 2.5.1
            Reporter: Joseph Prosser
            Assignee: Joseph Prosser
            Priority: Minor


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]
