Sergey Soldatov commented on HBASE-11839:
-----------------------------------------
Some additional information:
StochasticBalancer creates a plan which is using actions how to move regions
across the server. At the time of creation it doesn't check whether the
destination server is available or not. In the test one of the servers is
deleted, so plan includes actions where the destination is not working. When
AssignmentManager find such actions it replaces it with random destination.
So, the result of this test is completely unpredictable. I believe that the
problem is where the Plan is created and somehow the update of valid
destinations is missed. Need a bit more time to understand where it should be.
Any suggestions or comments are welcome
