Subject [jira] [Updated] (MAPREDUCE-6007) Create a new option for distcp -p which causes raw.* namespace extended attributes to not be preserved
Date Thu, 31 Jul 2014 22:05:38 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-6007?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Charles Lamb updated MAPREDUCE-6007:
------------------------------------

    Attachment: MAPREDUCE-6007.001.patch

A patch is attached which adds a "d" option to distcp -p. "d" is Disable raw.* namespace xattr
preservation. Refer to the document attached to HDFS-6509 for more details on the motivation
for this.

I've also taken the liberty to create a new DistCpTestUtils file to hold common methods for
distcp tests.

Please have a look.

> As part of the Data at Rest Encryption work (HDFS-6134), we need to create a new option
for distcp which causes raw.* namespace extended attributes to not be preserved. See the doc
in HDFS-6509 for details. The default for this option will be to preserve raw.* xattrs.
