> 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
