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

             Summary: DataXceiver#run() should not log exceptions caused by InvalidToken exception as an error
                 Key: HDFS-14231
                 URL: https://issues.apache.org/jira/browse/HDFS-14231
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: hdfs
    Affects Versions: 3.1.1
            Reporter: Kitti Nanasi
            Assignee: Kitti Nanasi


HDFS-10760 changed the log level from error to trace in DataXceiver#run() if the exception was an InvalidToken exception. I think it would be beneficial to log on trace level if the exception's cause was InvalidException. Like in the following case:
{code:java}
DataXceiver error processing unknown operation 
src: xxx dst: xxx
javax.security.sasl.SaslException: DIGEST-MD5: IO error acquiring password [Caused by org.apache.hadoop.security.token.SecretManager$InvalidToken: Block token with block_token_identifier
(expiryDate=1547593336220, keyId=-1735471718, userId=hbase, blockPoolId=BP-xxx, blockId=1245599303, access modes=[READ]) is expired.]
{code}
