             Summary: Print a warning if AccessControlEnforcer runs for a long 
time to check permission
                 Key: HDFS-16881
                 URL: https://issues.apache.org/jira/browse/HDFS-16881
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: namanode
            Reporter: Tsz-wo Sze
            Assignee: Tsz-wo Sze


AccessControlEnforcer is configurable.  If an external AccessControlEnforcer 
runs for a long time to check permission with the FSnamesystem lock, it will 
significantly slow down the entire Namenode.  In the JIRA, we will print a WARN 
message when it happens.
