Hi, Kiran Welcome to beautiful world of HBase transition states :) . When i face RIT issue this are steps that i use to resolve it:
1. hbase hbck -fixAssignments (this depends on your version of hbase it can be also just -fix) If you don't have luck with 1. then you will need manual intervention: Remove hbase znodes from zookeeper (use hbase zkcli) and options rmr (or delete ) /hbase, and then restart cluster. This should help you resolve RITs.
