[jira] [Updated] (MAPREDUCE-6040) distcp should automatically use /.reserved/raw when run by the superuser

     [ https://issues.apache.org/jira/browse/MAPREDUCE-6040?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Charles Lamb updated MAPREDUCE-6040:
------------------------------------

    Description: 
On HDFS-6134, [~sanjay.radia] asked for distcp to automatically prepend /.reserved/raw if the distcp is being performed by the superuser and /.reserved/raw is supported by both the source and destination filesystems. This behavior only occurs if none of the src and target pathnames are /.reserved/raw.

The -disablereservedraw flag can be used to disable this option.

Naturally, we'd also want a flag to disable this behavior.

        Summary: distcp should automatically use /.reserved/raw when run by the superuser  (was: Automatically use /.reserved/raw when run by the superuser)
