Description
When i assign a region A the process is as follows:
step1 : A is assigned to rs1 , and rs1 fails to open it .
step2 : assignProcedure handleFailure .
step3 : A is assign to rs2 and rs success to open it .
Above is the normal flow . However when rs1 is restart after the reigon A was split and GCRegionProcedure was successed , the region A appare again !
The region is that reigon A is not removed from the serverMap correctly when assignprocedure handleFailure . Because the code regionNode.offline() make the regionNode's regionLocation to be null and make regionNode's state to OFFLINE . So when the code env.getAssignmentManager().undoRegionAsOpening(regionNode) do nothing . So when the rs1 restart event triggers a serverCrashProcedure, it will get reigons from serverMap and it will get the region A then A will be assigned and hdfs dir will be created.
