Aihua Xu reassigned HIVE-10021: ------------------------------- Assignee: Aihua Xu > "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 > Attachments: 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. > Example stack trace from the HiveServer2 logs: > {noformat} > FAILED: NullPointerException null > java.lang.NullPointerException > at >
