I've setup a Hbase cluster with two nodes and I've noticed the warning "AssignmentManager: STUCK Region-In-Transition" which is not allowing the master to startup.



Node 1: observepreserve.corp.com (Master / Zookeeper)
Node 2: knewshoe.corp.com (Region Server)



Why it is happeneing and how to fix it?



Under Hbase UI I can see the below message.
