Function

Use the REST service to transfer the URL consisting of the host and port to obtain the cluster version and status information through HTTPS.

Example Code

• Obtaining the cluster version information

  The following code snippets are in the getClusterVersion method in the HBaseRestTest class of the hbase-rest-example\src\main\java\com\huawei\hadoop\hbase\examples packet.

  private void getClusterVersion(String url) {
       String endpoint = "/version/cluster";
       Optional<ResultModel> result = sendAction(url + endpoint, MethodType.GET, null);
       handleNormalResult((Optional<ResultModel>) result);
   }

• Obtaining the cluster status information

  The following code snippets are in the getClusterStatus method in the HBaseRestTest class of the hbase-rest-example\src\main\java\com\huawei\hadoop\hbase\examples packet.

  private void getClusterStatus(String url) {
       String endpoint = "/status/cluster";
       Optional<ResultModel> result = sendAction(url + endpoint, MethodType.GET, null);
       handleNormalResult(result);
   }
