> Following tests are failing consistently and are reproducible on master:
> * testVersionMatching
> * testMetastoreVersion
> I tried debugging it and found that ObjectStore.getMSSchemaVersion() throws an exception
{{No matching version found}}. 
> To fetch schema version this method executes {code:sql} SELECT FROM org.apache.hadoop.hive.metastore.model.MVersionTable
{code} but for whatever reason execution returns empty result set resulting in the exception.
Both test failures are due to this exception. I tried debugging the query execution but didn't
really go nowhere with it. I suspect this could be due to recent metastore changes. I tried
reproducing this outside test but with no success.
