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

org.apache.hadoop.hbase.master.AssignmentManager.regionOffline()
Marks the region as offline. Removes it from regions in transition and removes in-memory assignment information.
Used when a region has been closed and should remain closed. @param regionInfo
