> --------------------------------------------------------------------------

> Key: HIVE-18322
> URL: https://issues.apache.org/jira/browse/HIVE-18322
> Project: Hive
> Issue Type: Bug
> Reporter: Thejas Nair
> Priority: Major
>
> As commented in HIVE-17853 , RetryingMetaStoreClient should also check to see
> if current user is same as the original UGI user, and not do the ugi.doAs()
> if it is the same. Otherwise, this can potentially cause problems where the
> users are not privileged users (ie, there is no intent to do a "doAs").
> Without such a check, you would get errors like " userX is not allowed to
> impersonate userX".
