> If a failure happens in split before OFFLINING_PARENT, we tend to rollback the split
including deleting the znodes created.
> On deletion of the RS_ZK_SPLITTING node we are getting a callback but not remvoving from
RIT. We need to remove it from RIT, anyway SSH logic is well guarded in case the delete event
comes due to RS down scenario.
