Examples with GetBlockResponseProto org.apache.hadoop.hdds.protocol.datanode.proto.ContainerProtos.GetBlockResponseProto used on opensource projects

Example 1 with GetBlockResponseProto

use of org.apache.hadoop.hdds.protocol.datanode.proto.ContainerProtos.GetBlockResponseProto in project ozone by apache.

the class ContainerProtocolCalls method getBlockFromAllNodes.

public static HashMap<DatanodeDetails, GetBlockResponseProto> getBlockFromAllNodes(XceiverClientSpi xceiverClient, DatanodeBlockID datanodeBlockID, Token<OzoneBlockTokenIdentifier> token) throws IOException, InterruptedException {
    GetBlockRequestProto.Builder readBlockRequest = GetBlockRequestProto.newBuilder().setBlockID(datanodeBlockID);
    HashMap<DatanodeDetails, GetBlockResponseProto> datanodeToResponseMap = new HashMap<>();
    String id = xceiverClient.getPipeline().getFirstNode().getUuidString();
    ContainerCommandRequestProto.Builder builder = ContainerCommandRequestProto.newBuilder().setCmdType(Type.GetBlock).setContainerID(datanodeBlockID.getContainerID()).setDatanodeUuid(id).setGetBlock(readBlockRequest);
    if (token != null) {
        builder.setEncodedToken(token.encodeToUrlString());
    }
    ContainerCommandRequestProto request = builder.build();
    Map<DatanodeDetails, ContainerCommandResponseProto> responses = xceiverClient.sendCommandOnAllNodes(request);
    for (Map.Entry<DatanodeDetails, ContainerCommandResponseProto> entry : responses.entrySet()) {
        datanodeToResponseMap.put(entry.getKey(), entry.getValue().getGetBlock());
    }
    return datanodeToResponseMap;
}

Example 2 with GetBlockResponseProto

use of org.apache.hadoop.hdds.protocol.datanode.proto.ContainerProtos.GetBlockResponseProto in project ozone by apache.

the class BlockInputStream method getChunkInfos.

/**

 * @return List of chunks in this block.
 */

    // protocol.
