> In the Sql transformers, a new temp view with a random name is created for each incoming batch, but the temp view is never dropped.
> This causes a resource leak in Spark SessionState's Catalog. For long-running deltastreamer jobs, the temp views created causes HiveSessionCatalog to take up a lot of memory.
