Subject [jira] [Commented] (HDFS-6039) Uploading a File under a Dir with default acls throws "Duplicated ACLFeature"
Date Mon, 03 Mar 2014 19:14:21 GMT

    [ https://issues.apache.org/jira/browse/HDFS-6039?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13918446#comment-13918446
] 

Chris Nauroth commented on HDFS-6039:
-------------------------------------

The problem here is that we're mishandling renames. hdfs dfs -copyFromLocal first creates
the file in a temporary location. In this case it's /tmp/HDFSAcls/Dir-0/Child_file.COPYING.
Then, after creation is successful, it renames to the final destination. The problem is that
we copied the default ACL during the initial create, and then we tried to copy it again during
the rename, resulting in this Duplicated ACLFeature error.
