Subject [jira] [Commented] (HADOOP-10919) Copy command should preserve raw.* namespace extended attributes
Date Tue, 12 Aug 2014 01:08:12 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-10919?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14093594#comment-14093594
] 

Sanjay Radia commented on HADOOP-10919:
---------------------------------------

charles, what is the usage model for distcp of encrypted files:
* distcp path1 path2   - where distcp will insert /.reserved/.raw to the pathnames if in encrypted
zone.
* OR distcp /.reserved/.raw/path1  /.reserved/.raw/path2


BTW is the proposal is that both src and dest MUST be encryptedZones or neither ? (Because
of your "misspoke" comment I am a little confused.)

> Like distcp -p (see MAPREDUCE-6007), the copy command also needs to preserve extended
attributes in the raw.* namespace by default whenever the src and target are in /.reserved/raw.
To not preserve raw xattrs, don't specify /.reserved/raw in either the src or target.
