Constructor Detail

ClusterProcessor

public ClusterProcessor(GridKernalContext ctx)

Parameters:

ctx - Kernal context.

Method Detail

diagnosticEnabled

public boolean diagnosticEnabled()

Returns:

Diagnostic flag.

initDiagnosticListeners

public void initDiagnosticListeners()
                             throws IgniteCheckedException

Throws:

IgniteCheckedException - If failed.

diagnosticLog

public IgniteLogger diagnosticLog()

Returns:

Logger for diagnostic category.

get

public IgniteClusterImpl get()

Returns:

Cluster.

clientReconnectFuture

public IgniteFuture<?> clientReconnectFuture()

Returns:

Client reconnect future.

discoveryDataType

@Nullable
public @Nullable GridComponent.DiscoveryDataExchangeType discoveryDataType()

Gets unique component type to distinguish components providing discovery data. Must return non-null value if component implements any of methods GridComponent.collectJoiningNodeData(DiscoveryDataBag) or GridComponent.collectGridNodeData(DiscoveryDataBag).

Specified by:

discoveryDataType in interface GridComponent

Overrides:

discoveryDataType in class GridProcessorAdapter

Returns:

Unique component type for discovery data exchange.

collectJoiningNodeData

public void collectJoiningNodeData(DiscoveryDataBag dataBag)

Collects discovery data on joining node before sending TcpDiscoveryJoinRequestMessage request.

Specified by:

collectJoiningNodeData in interface GridComponent

Overrides:

collectJoiningNodeData in class GridProcessorAdapter

Parameters:

dataBag - container object to store discovery data in.

collectGridNodeData

public void collectGridNodeData(DiscoveryDataBag dataBag)

Collects discovery data on nodes already in grid on receiving TcpDiscoveryNodeAddedMessage.

Specified by:

collectGridNodeData in interface GridComponent

Overrides:

collectGridNodeData in class GridProcessorAdapter

Parameters:

dataBag - container object to store discovery data in.

onGridDataReceived

public void onGridDataReceived(DiscoveryDataBag.GridDiscoveryData data)

Receives discovery data object from remote nodes (called on new node during discovery process).

Specified by:

onGridDataReceived in interface GridComponent

Overrides:

onGridDataReceived in class GridProcessorAdapter

Parameters:

data - DiscoveryDataBag.GridDiscoveryData interface to retrieve discovery data collected on remote nodes (data common for all nodes in grid and specific for each node).

onKernalStart

public void onKernalStart(boolean active)
                   throws IgniteCheckedException

Callback that notifies that kernal has successfully started, including all managers and processors.

Specified by:

onKernalStart in interface GridComponent

Overrides:

onKernalStart in class GridProcessorAdapter

Parameters:

active - Cluster active flag (note: should be used carefully since state can change concurrently).

Throws:

IgniteCheckedException - Thrown in case of any errors.

stop

public void stop(boolean cancel)
          throws IgniteCheckedException

Stops grid component.

Specified by:

stop in interface GridComponent

Overrides:

stop in class GridProcessorAdapter

Parameters:

cancel - If true, then all ongoing tasks or jobs for relevant components need to be cancelled.

Throws:

IgniteCheckedException - Thrown in case of any errors.

disableUpdateNotifier

public void disableUpdateNotifier()

Disables update notifier.

updateNotifierEnabled

public boolean updateNotifierEnabled()

Returns:

Update notifier status.

latestVersion

public String latestVersion()

Returns:

Latest version string.

clusterName

public String clusterName()

Get cluster name.

Returns:

Cluster name.

requestDiagnosticInfo

public IgniteInternalFuture<String> requestDiagnosticInfo(UUID nodeId,
                                                          IgniteClosure<GridKernalContext,IgniteDiagnosticInfo> c,
                                                          String baseMsg)

Sends diagnostic message closure to remote node. When response received dumps remote message and local communication info about connection(s) with remote node.

Parameters:

nodeId - Target node ID.

c - Closure to send.

baseMsg - Local message to log.

Returns:

Message future.
