YARN-11891. Yarn logs command hangs for running applications

[dmmkr]

Description of PR

JIRA: YARN-11891. Yarn logs command hangs for running applications.

filter() method inside the ClientJerseyRetryFilter class, calls checkUrlConnectivity() in a while loop, If there is any issue with connectivity, it decrements the leftRetries till it becomes 0 and throws an Exception, but if it succeeds it keeps on spinning inside the infinite while loop, so added a return after checkUrlConnectivity().

After fixing the above issue, the yarn logs command was throwing below error.

Can not find any log file matching the pattern: [ALL] for the container: container_id within the application: app_id

The XML response of /ws/v1/node/containers/<container_id>/logs is

So in getContainerLogFiles(), an additional getJSONObject("containerLogsInfoes") has been added to ensure the XML response is parsed properly

How was this patch tested?

Validated yarn logs -applicationId for running and completed applications.

For code changes:

• Does the title or this PR starts with the corresponding JIRA issue id (e.g. 'HADOOP-17799. Your PR title ...')?
• Object storage: have the integration tests been executed and the endpoint declared according to the connector-specific documentation?
• If adding new dependencies to the code, are these dependencies licensed in a way that is compatible for inclusion under ASF 2.0?
• If applicable, have you updated the LICENSE, LICENSE-binary, NOTICE-binary files?
