Chao updated HIVE-10021:
------------------------
Description:
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.
