Description

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.
