Subject [jira] [Commented] (HADOOP-1540) distcp should support an exclude list
Date Thu, 07 May 2015 01:22:00 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-1540?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14531848#comment-14531848

Rich Haase commented on HADOOP-1540:
------------------------------------

Found a bug in the patch.  The CopyCommitter doesn't know about exclusions so it will throw
an exception when it tries to preserve permissions on a Path that was excluded.  Need to refactor
the change to separate exclusion logic into a class that is usable by the CopyMapper and CopyCommiter.
 Since the code has to be refactored to work correctly it makes sense to define an interface
for exclusions.

> There should be a way to ignore specific paths (eg: those that have already been copied
over under the current srcPath).
