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

             Summary: Log at INFO level when InvalidToken is seen in 
ShortCircuitCache
                 Key: HDFS-7394
                 URL: https://issues.apache.org/jira/browse/HDFS-7394
             Project: Hadoop HDFS
          Issue Type: Bug
            Reporter: Kihwal Lee
            Priority: Minor


For long running clients, getting an {{InvalidToken}} exception is expected and 
the client refetches a block token when it happens.  The related events are 
logged at INFO except the ones in {{ShortCircuitCache}}.  It will be better if 
they are also made to log at INFO.
