Examples of org.apache.hadoop.hbase.master.AssignmentManager.assign()

org.apache.hadoop.hbase.master.AssignmentManager.assign()
Assigns the specified region.
If a RegionPlan is available with a valid destination then it will be used to determine what server region is assigned to. If no RegionPlan is available, region will be assigned to a random available server.
Updates the RegionState and sends the OPEN RPC.
This will only succeed if the region is in transition and in a CLOSED or OFFLINE state or not in transition (in-memory not zk), and of course, the chosen server is up and running (It may have just crashed!). If the in-memory checks pass, the zk node is forced to OFFLINE before assigning. @param region server to be assigned @param setOfflineInZK whether ZK node should be created/transitioned to anOFFLINE state before assigning the region
