I just simply tested the command.
I connected to STS via beeline by using session user different from the user
who started STS.After running the create table command, I check the owner of
hdfs path which is the session user.
When I tried to drop table owned by user who started STS and got permission
denied exception.
For DML, their is opened issue:
https://issues.apache.org/jira/browse/SPARK-5159.
I can fix those issue together if necessary

> HiveClient shouldn't share Hive object between different thread
> ---------------------------------------------------------------
>
> Key: SPARK-21918
> URL: https://issues.apache.org/jira/browse/SPARK-21918
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.2.0
> Reporter: Hu Liu,
>
> I'm testing the spark thrift server and found that all the DDL statements are
> run by user hive even if hive.server2.enable.doAs=true
> The root cause is that Hive object is shared between different thread in
> HiveClientImpl
> {code:java}
> private def client: Hive = {
> if (clientLoader.cachedHive != null) {
> clientLoader.cachedHive.asInstanceOf[Hive]
> } else {
> val c = Hive.get(conf)
> clientLoader.cachedHive = c
> c
> }
> }
> {code}
> But in impersonation mode, we should just share the Hive object inside the
> thread so that the metastore client in Hive could be associated with right
> user.
> we can pass the Hive object of parent thread to child thread when running
> the sql to fix it
> I have already had a initial patch for review and I'm glad to work on it if
> anyone could assign it to me.
