Hive implementation should fail by default when it connects to a local metastore.

Currently, the Hive integration issues a warning when it connects to a local metastore. This is easy to ignore and in some cases gets removed. A user recently had this problem but Oozie was suppressing the warning message. The default should be to fail if the metastore can't be found rather than connecting to a local metastore that either appears to work (for dataset creation) but doesn't or appears to fail for no reason (can't find table on dataset load).

This was implemented for CDK-483, PR #107 but removed until this was a problem in practice.
