> Project: ZooKeeper
> Issue Type: Improvement
> Affects Versions: 3.4.10, 3.5.3
> Reporter: Pan Yuxuan
> Assignee: Pan Yuxuan

>
> 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.
