[jira] [Created] (HDFS-6734) Reduce number of AclException messages in NN log when ACLs are disabled

Andrew Wang created HDFS-6734:
---------------------------------

             Summary: Reduce number of AclException messages in NN log when ACLs are disabled
                 Key: HDFS-6734
                 URL: https://issues.apache.org/jira/browse/HDFS-6734
             Project: Hadoop HDFS
          Issue Type: Improvement
    Affects Versions: 2.5.0
            Reporter: Andrew Wang


The FsShell's Ls operation queries ACLs when it lists paths. The AclException is listed as a terse exception in NameNodeRpcServer (HDFS-6069), but still ends up printing a log message.

As a suggestion, when ACLs are disabled, we could print a single message on startup indicating that ACLs are disabled, not print anything for getAclStatus calls, and print a terse exception for modify ACL commands.
