---------------------------------
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.
