---------------------------------------
[~csun], your commit does not include the JIRA number (although it has the same
title so the issue is easy to find). I'll add it to the errata list in the
thread "Please double-check JIRA number on commit" on dev@hive.

> "Alter index rebuild" statements submitted through HiveServer2 fail when
> Sentry is enabled
> ------------------------------------------------------------------------------------------

> Key: HIVE-10021
> URL: https://issues.apache.org/jira/browse/HIVE-10021
> Project: Hive
> Issue Type: Bug
> Components: HiveServer2, Indexing
> Affects Versions: 0.13.1, 2.0.0
> Environment: CDH 5.3.2
> Reporter: Richard Williams
> Assignee: Aihua Xu
> Fix For: 1.3.0, 2.0.0

> Attachments: HIVE-10021.2.patch, HIVE-10021.patch

>
> When HiveServer2 is configured to authorize submitted queries and statements
> through Sentry, any attempt to issue an "alter index rebuild" statement fails
> with a SemanticException caused by a NullPointerException. This occurs
> regardless of whether the index is a compact or bitmap index.
> The root cause of the problem appears to be the fact that the static
> createRootTask function in org.apache.hadoop.hive.ql.optimizer.IndexUtils
> creates a new
> org.apache.hadoop.hive.ql.Driver object to compile the index builder query,
> and this new Driver object, unlike the one used by HiveServer2 to compile the
> submitted statement, is used without having its "userName" field initialized
> with the submitting user's username. Adding null checks to the Sentry code is
> insufficient to solve this problem, because Sentry needs the userName to
> determine whether or not the submitting user should be able to execute the
> index rebuild statement.
