Tim Armstrong resolved IMPALA-3362.
-----------------------------------
Resolution: Won't Fix
I think this is referring to the "kinit" invocation. We removed these a part of
IMPALA-5734
> Take steps to be more secure when invoking external commands

>
> Key: IMPALA-3362
> URL: https://issues.apache.org/jira/browse/IMPALA-3362
> Project: IMPALA
> Issue Type: Task
> Components: Security
> Affects Versions: Impala 2.5.0
> Reporter: Sailesh Mukil
> Priority: Minor
> Labels: security
>
> When we execute external commands, we execute them under the same context of
> the user that is running Impala. We typically would want to make sure we run
> the external command under a different context. One solution is to do a
> setgid() before we do so. This isn't a big problem as Impala is not run as a
> privileged process.
