org.apache.hadoop.hbase.client.HBaseAdmin.unassign()
Unassign a region from current hosting regionserver. Region will then be assigned to a regionserver chosen at random. Region could be reassigned back to the same server. Use {@link #move(byte[],byte[])} if you wantto control the region movement. @param regionName Region to unassign. Will clear any existing RegionPlanif one found. @param force If true, force unassign (Will remove region fromregions-in-transition too if present. If results in double assignment use hbck -fix to resolve. To be used by experts). @throws MasterNotRunningException @throws ZooKeeperConnectionException @throws IOException
