-------------------------------------
Summary: ZooKeeperSaslClient#respondToServer should log exception
message of SaslException
Key: ZOOKEEPER-2856
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-2856
Project: ZooKeeper
Issue Type: Improvement
Affects Versions: 3.5.3, 3.4.10
Reporter: Pan Yuxuan
Priority: Minor
When upstream like HBase call ZooKeeperSaslClient with security enabled, we
sometimes get error in HBase logs like:
{noformat}
SASL authentication failed using login context 'Client'.
{noformat}
This error occures when getting SaslException in
ZooKeeperSaslClient#respondToServer :
{noformat}
catch (SaslException e) {
LOG.error("SASL authentication failed using login context '" +
this.getLoginContext() + "'.");
saslState = SaslState.FAILED;
gotLastPacket = true;
}
{noformat}
This error makes user confused without explicit exception message. So I think
we can add exception message to the log.
