Subject [jira] [Commented] (MAPREDUCE-5014) Extending DistCp through a custom CopyListing is not possible
Date Fri, 22 Mar 2013 04:19:16 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-5014?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13609900#comment-13609900

Tsz Wo (Nicholas), SZE commented on MAPREDUCE-5014:
---------------------------------------------------

> -1 one of tests included doesn't have a timeout.

The test without timeout is an existing test.  The test-patch.sh should not -1 on this patch.
 I think it is a bug in HADOOP-9387.

> * While it is possible to implement a custom CopyListing in DistCp, DistCp driver class
doesn't allow for using this custom CopyListing.
> * Allow SimpleCopyListing to provide an option to exclude files (For instance it is useful
to exclude FileOutputCommiter.SUCCEEDED_FILE_NAME during copy as premature copy can indicate
that the entire data is available at the destination)
