Hi Ali,
I used ClusterAction for my case because I had to execute action on all
nodes. I used something like this
public class CustomAction extends
ClusterAction<CustomRequest, CustomResponse, CustomRequestBuilder>{
... implement all required methods (override newRequestBuilder and
newResponse) ...
public class CustomNodeResponse extends NodeOperationResponse {
}
public class CustomRequest extends NodesOperationRequest<CustomRequest> {
... overide writeTo and readFrom methods ...
... add custom data fields in this class ... (for example I used "id" which
was given in constructor and read/write in overridden methods ...
public class CustomRequestBuilder extends
NodesOperationRequestBuilder<CustomRequest,
CustomResponse, CustomRequestBuilder> {
... override doExecute method. I used something below ...
@Override
protected void doExecute(ActionListener<CustomResponse> listener) {
client.execute(CustomAction.INSTANCE, request, listener);
}
public class CustomResponse extends
NodesOperationResponse<NodeCustomResponse> {
... implement writeTo and readFrom methods ...
public class NodeCustomResponse extends NodeOperationResponse {
... implement writeTo and readFrom methods ...
And finally the most important part
public class TransportCustomAction extends
TransportNodesOperationAction<CustomRequest, CustomResponse,
TransportCustomAction.NodeCustomRequest, NodeCustomResponse> {
... the main part is in nodeOperation method. here is implementation of
your action ...
