Chris Nauroth updated MAPREDUCE-5809:
-------------------------------------
Attachment: MAPREDUCE-5809.4.patch
I'm attaching patch v4. This implements Nicholas's suggestion to store the
ACLs in the copy listing file for use by {{CopyCommitter}}. Additional changes
to this patch will come after we resolve HDFS-6326.
bq. If we cannot change FileStatus for backwards-compatibility, how about add
new FileSystem methods such as listStatusWithACL(..) which returns
FileStatusWithACL?
I'd like to have a follow-up discussion about possibly adding batch APIs to
improve distcp performance, and this is one of them that I had in mind. Can we
please postpone this until later, since it's a performance optimization and not
a correctness issue? The current patch is already large, and adding new API
definitions and the RPC calls to back them would likely double it.
