> 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().
