> Key: HIVE-10021

> Project: Hive
> Issue Type: Bug

> Affects Versions: 0.13.1

> 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.
