Subject [jira] [Commented] (HADOOP-10919) Copy command should preserve raw.* namespace extended attributes
Date Tue, 12 Aug 2014 00:32:12 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-10919?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14093557#comment-14093557
] 

Charles Lamb commented on HADOOP-10919:
---------------------------------------

bq. Charles, you list disadvantage for the .raw scheme where the target of a distcp is not
an encrypted zone. Would it make sense for distcp to check for that and to fail the distcp?

Hi Sanjay,

Presently distcp requires both src and target to be either both in /.reserved/raw or neither
in /.reserved/raw.

I'll update the HDFS-6509 document and comments.

Thanks for catching that.

> 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.
