Description

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 the stack:
