>                 URL: https://issues.apache.org/jira/browse/HAWQ-1269
>             Project: Apache HAWQ
>          Issue Type: Bug
>          Components: Security
>            Reporter: Paul Guo
>            Assignee: Lin Wen
>            Priority: Minor
>
> We occasionally saw kerberos authentication fails during some tests, then psql will report the message below,
> {noformat}
> psql: server closed the connection unexpectedly
>         This probably means the server terminated abnormally
>         before or while processing the request.
> {noformat}
> Not sure whether the kerberos service at that time is broken, or there is something wrong with the GSSAPI library or there is something wrong of kerberos coding in hawq, but at least hawq should not simply "close the connection".
> There is no obvious related log on the master side. It is hard to reproduce this. I'd log here so that people who see similar issue could  provide more contexts here (repro case, etc).
> Probably we should upgrade gss related libraries.
> It seems that one of the related functions is gss_accept_sec_context()
