zhangqw updated SPARK-18641:
----------------------------
Summary: Show databases NullPointerException while Sentry turned on (was:
Show databases NullPointerException while sentry turned on)
> Show databases NullPointerException while Sentry turned on
> ----------------------------------------------------------
>
> Key: SPARK-18641
> URL: https://issues.apache.org/jira/browse/SPARK-18641
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.0.0
> Environment: CentOS 6.5 / Hive 1.1.0 / Sentry 1.5.1
> Reporter: zhangqw
>
> I've traced into source code, and it seems that <hive.sentry.subject.name> of
> Sentry not set when spark sql started a session. This operation should be
> done in org.apache.sentry.binding.hive.HiveAuthzBindingSessionHook which is
> not called in spark sql.
> Edit: I copyed hive-site.xml(which turns on Sentry) and all sentry jars into
> spark's classpath.
> Here is thestack:
