Description

One of our tests removes the hdfs directory for the region, and invokes HBCK to fix the issue. This test fails flakily because the region is removed from meta and unassigned, but the region is not offlined from the masters in-memory. This affects further LB runs and disable table, etc.

In case of inMeta && !inHdfs && isDeployed, we should not just close the region from RS, but call master.unassign().
