Examples of org.apache.hadoop.hbase.client.Admin.unassign()

org.apache.hadoop.hbase.client.Admin.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 want to control the region movement. @param regionName Region to unassign. Will clear any existing RegionPlan if one found. @param force If true, force unassign (Will remove region from regions-in-transition too ifpresent. If results in double assignment use hbck -fix to resolve. To be used by experts). @throws MasterNotRunningException @throws ZooKeeperConnectionException @throws IOException
