Tsz Wo Nicholas Sze commented on MAPREDUCE-5809:
------------------------------------------------
- CopyCommitter should not get and use source FileSystem since it will be much
slower. We should change listing SequenceFile value to something like
FileStatusWithACL (a new class). Then, CopyCommitter could read ACL from it.
- Should AclsNotSupportedException extend IOException instead of
RuntimeException?
- Let's move AclsNotSupportedException and
DistCpUtils.checkFileSystemAclSupport(..) to Common. They are also useful for
other cases.
> Enhance distcp to support preserving HDFS ACLs.
