> Any region in FAILED_OPEN state has to be manually reassigned, or the master can be restarted and this will also cause reattempt of assignment of any regions in FAILED_OPEN state. This is not unexpected but is an operational headache. It would be better if the RSGroupInfoManager could automatically kick reassignments of regions in FAILED_OPEN state when servers rejoin the cluster.
