Yes, we leak connections. There is a fix in Hive for [closing before
reconnecting](https://github.com/apache/hive/commit/8fb805225c9d6960c7d39d862de6b3326650551c),
but that is in a later version.
Also, there is another leak. The
[HiveStoragePlugin](https://github.com/apache/drill/blob/master/contrib/storage-hive/core/src/main/java/org/apache/drill/exec/store/hive/HiveStoragePlugin.java)
does not close connections (in HiveSchemaRegistry) when close is invoked. This
should be done in an overridden close method.
