Navis commented on HIVE-3518:
-----------------------------
QTestUtil creates new HiveConf per test for removing side effects but it's not
propagated to entities like SessionState or MetaStoreClient. The patch is
fixing it and not yet tested. After that I'll mark this patch-available.

> Flushing 'hive.metastore.pre.event.listeners' into empty string solves the
> issue. During debugging I figured out this property wan't cleaned for other
> tests after it was set in metadata_export_drop.q.
> How to reproduce:
> {code} ant test -Dtestcase=TestCliDriver -Dqfile=metadata_export_drop.q,<some
> test>.q{code}
> where <some test>.q means any test which contains CREATE statement. For
> example, sample10.q
