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

Adding logging to LeaseRenewer for better lease expiration triage.
------------------------------------------------------------------

                 Key: HDFS-2803
                 URL: https://issues.apache.org/jira/browse/HDFS-2803
             Project: Hadoop HDFS
          Issue Type: Improvement
            Reporter: Jimmy Xiang
            Priority: Minor


It 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 will be hard to know
if a DFS client doesn't renew the lease because it hangs, or the lease renewer daemon is gone somehow.
