[jira] [Created] (ZOOKEEPER-2344) Provide more diagnostics/stack traces on SASL Auth failure

Steve Loughran created ZOOKEEPER-2344:
-----------------------------------------

             Summary: Provide more diagnostics/stack traces on SASL Auth failure
                 Key: ZOOKEEPER-2344
                 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-2344
             Project: ZooKeeper
          Issue Type: Improvement
          Components: java client, server
    Affects Versions: 3.4.5
            Reporter: Steve Loughran


When Kerberos decides it doesn't want to work, the JRE libraries provide some terse and unhelpful error messages.

The only way to debug the problem is (a) to have complete stack traces and (b) as much related information as possible.

Zookeeper could do more here. Currently too much of the code loses stack traces; sometimes auth errors aren't reported back to the client (the connection is closed) +others

Everyone who has tried to diagnose kerberos problems will appreciate improvements here
