Kitti Nanasi created HDFS-14231:
-----------------------------------
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}
