[jira] [Updated] (HDFS-2803) Adding logging to LeaseRenewer for better lease expiration triage.

["Jimmy Xiang (Updated) (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/HDFS-2803?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Jimmy Xiang updated HDFS-2803:
------------------------------

    Description: 
It will be helpful to add some logging to LeaseRenewer when the daemon is terminated (Info level),
and when the lease is renewed (Debug level).  Since lacking logging, it is hard to know
if a DFS client doesn't renew the lease because it hangs, or the lease renewer daemon is gone somehow.
