-----------------------------
Assignee: Vincent Devillers
> Implement Closeable for deallocable resources
> ---------------------------------------------
>
> Key: KNOX-806
> URL: https://issues.apache.org/jira/browse/KNOX-806
> Project: Apache Knox
> Issue Type: Improvement
> Components: ClientDSL
> Reporter: Vincent Devillers
> Assignee: Vincent Devillers
> Priority: Minor
>
> org.apache.hadoop.gateway.shell.BasicResponse and
> org.apache.hadoop.gateway.shell.Hadoop are not java.io.Closeable, which means
> that we have to do this:
> {code:java}
> BasicResponse response = null;
> String jobId;
> try {
> response = Workflow.submit(getHadoop()).text(xmlConfiguration).now();
> jobId = JsonPath.read(response.getString(), "$.id");
> } finally {
> if(response != null) {
> response.close();
> }
> }
> {code}
> instead of this:
> {code:java}
> String jobId;
> try (BasicResponse response =
> Workflow.submit(getHadoop()).text(xmlConfiguration).now()){
> jobId = JsonPath.read(response.getString(), "$.id");
> }
> {code}
