Subject [jira] [Commented] (MAPREDUCE-5809) Enhance distcp to support preserving HDFS ACLs.
Date Mon, 05 May 2014 01:40:17 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-5809?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13989235#comment-13989235
] 

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.
