----------------------------------

             Summary: FLumeAuthenticator.startCredentialRefresher is not called in HDFS sink source
                 Key: FLUME-2845
                 URL: https://issues.apache.org/jira/browse/FLUME-2845
             Project: Flume
          Issue Type: Bug
          Components: Sinks+Sources
    Affects Versions: v1.6.0
            Reporter: stanley shi


I have a long running service which uses HDFS sink to push data to a Kerberos-enabled HDFS cluster.
However, the HDFS sink always fail after 10 hours running saying something like:
16 Nov 2015 10:32:54,400 WARN  (org.apache.hadoop.security.UserGroupInformation.hasSufficientTimeElapsed:1168)  - Not attempting to re-login since the last re-login was attempted less than 600 seconds before.

And then later followed by some " GSS initiate failed".

I checked the FlumeAuthenticator and found that there's a method "startCredentialRefresher" which will spawn a new thread to do relogin.
I believe this method should be called in the HDFSEventSink.
