    Description

      Unit and integration tests for functional areas where the implementation wraps scanners and uses a delegate pattern should check at the end of the test that no scanners were leaked (check that all scanners including the inner scanners were properly closed) by testing that the store reader reference count is zero on all stores.

      HBASE-22459 will offer a new metric and API which exposes this information.
