> 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}
