[jira] [Created] (YARN-10433) Extend the DiagnosticService to initiate the diagnostic bundle collection

Benjamin Teke created YARN-10433:
------------------------------------

             Summary: Extend the DiagnosticService to initiate the diagnostic bundle collection
                 Key: YARN-10433
                 URL: https://issues.apache.org/jira/browse/YARN-10433
             Project: Hadoop YARN
          Issue Type: Sub-task
            Reporter: Benjamin Teke
            Assignee: Benjamin Teke


YARN-10421 introduces the new DiagnosticService class, the two new endpoints for listing the available actions and starting the diagnostic script collect method, and a basic diagnostic collector script. After the scripts form is finalized (YARN-10422) the DiagnosticService should be extended to spawn the requested collection method based on the input parameters and return the collected bundle as a response.

To ease the load on the RM, the servlet should allow only one HTTP request at a time. If a new request comes in while serving another an appropriate response code should be returned, with the message "Diagnostics Collection in Progress”.
