```
public void onClusterVersionChange(Version newVersion)
```
    Description copied from interface: ClusterVersionListener
    
    Invoked on registered listeners after the new cluster version has been applied. Listeners are executed synchronously immediately after ClusterStateManager#version has been updated and while the cluster service lock ClusterServiceImpl#lock is still locked, as part of the commit phase of the transaction changing the cluster version. Unhandled exceptions from listeners implementation will break the new version commit and a slow implementation will stall the system and may cause a transaction timeout. If new cluster version is null and property GroupProperty.INIT_CLUSTER_VERSION is set, the version set by this property will be provided as argument to the listener. If neither are set, running node's codebase version will be used.
    
    Specified by:

  - createPartitionTableView
```
public PartitionTableView createPartitionTableView()
```
    Description copied from interface: InternalPartitionService
    
    Creates an immutable/readonly view of partition table.
    
    Specified by:
    
    createPartitionTableView in interface InternalPartitionService
    
    Returns:
    
    immutable view of partition table
  - isLocalMemberMaster
```
public boolean isLocalMemberMaster()
```
    Returns true only if local member is the last known master by InternalPartitionServiceImpl.
    Last known master is updated under partition service lock, when the former master leaves the cluster.
    This method should be used instead of node.isMaster() when the logic relies on being master.
  - isMemberMaster
```
public boolean isMemberMaster(Address address)
```
    Returns true only if the member is the last known master by InternalPartitionServiceImpl and ClusterServiceImpl.
    Last known master is updated under partition service lock, when the former master leaves the cluster.
  - commitMigrationOnDestination
```
public boolean commitMigrationOnDestination(MigrationInfo migration,
                                            Address sender)
