Querying Dump Details

Initialize a DIS SDK client instance named dic. For details, see Initializing a DIS SDK Client Instance.

You can use the DIS SDK to query the details of a specified dump task. The sample code is available in the TransferTaskDemo.java file under the dis-sdk-demo\src\main\java\com\bigdata\dis\sdk\demo\example directory.

DescribeTransferTaskRequest request = new DescribeTransferTaskRequest();

//Configure the name of the stream to be queried.
request.setStreamName(streamName);

//Configure the name of the dump task to be queried.
request.setTransferTaskName(taskName);

After configuring DescribeTransferTaskRequest, you can call the describeTransferTask method to query the details of a specified dump task.
