>
> Because RSGroups can cause permanent RIT with regions in FAILED_OPEN state,
> we added logic to the master portion of the RSGroups extention to enumerate
> RITs and retry assignment of regions in FAILED_OPEN state.
> However, this strategy can be applied generally to reduce need of operator
> involvement in cluster operations. Now an operator has to manually resolve
> FAILED_OPEN assignments but there is little risk in automatically retrying
> them after a while. If the reason the assignment failed has not cleared, the
> assignment will just fail again. Should the reason the assignment failed be
> resolved, then operators don't have to do more in order for the cluster to
> fully heal.
