List of unassign() Examples

Examples of unassign()

org.apache.accumulo.server.master.state.MetaDataStateStore.unassign()
org.apache.accumulo.server.master.state.ZooTabletStateStore.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
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
org.apache.hadoop.hbase.master.AssignmentManager.unassign()
Unassign the list of regions. Configuration knobs: hbase.bulk.waitbetween.reopen indicates the number of milliseconds to wait before unassigning another region from this region server @param regions @throws InterruptedException
