Tim Armstrong resolved IMPALA-3891.
-----------------------------------
Resolution: Cannot Reproduce
Unclear what this specifically referred to. I think many errors do get
propagated back to query status.
> send authentication error messages back to coordinator

> Key: IMPALA-3891
> URL: https://issues.apache.org/jira/browse/IMPALA-3891
> Project: IMPALA
> Issue Type: Improvement
> Components: Security
> Affects Versions: Impala 2.6.0
> Reporter: Huaisi Xu
> Priority: Major
>
> In Kerberos cluster, when authentication failed, Impala only prints error
> messages in logs, which is hard to find. It can be extremely frustrating when
> Impala hang/connection time out(after IMPALA-3875) at the same time.
> Instead, these messages should be sent back to the client.
