Chris Nauroth created HDFS-5737:
-----------------------------------

             Summary: Replacing only the default ACL can fail to copy 
unspecified base entries from the access ACL.
                 Key: HDFS-5737
                 URL: https://issues.apache.org/jira/browse/HDFS-5737
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: namenode
    Affects Versions: HDFS ACLs (HDFS-4685)
            Reporter: Chris Nauroth
            Assignee: Chris Nauroth


The final round of changes in HDFS-5673 switched to a search approach instead 
of a scan approach for finding base access entries that need to be copied to 
the default ACL.  However, in the case of doing full replacement on the default 
ACL, the list may not be sorted properly at this point in the code, causing the 
searches to miss the access entries.
