{code}
When drillbit is starting and StoragePluginRegistryImpl creates the
HIveStoragePlugin the DrillHiveMetaStoreClient is instantiated even when it is
disabled in the plugin template configs and there is no Hive on the machine.
The solution is to check status for plugin from the template, when it is
disabled there is no need to instantiate the client for the appropriate storage.
The workaround is to use "hive.metastore.schema.verification": "false", for
this case DrillHiveMetaStoreClient is created successfully (but for proper
working it should be performed only when plugin is enabled).
