### Description of PR
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
`<containerLogsInfoes>
<containerLogsInfo>
<containerLogInfo>
<fileName>stdout</fileName>
<fileSize>0</fileSize>
<lastModifiedTime>Wed Nov 05 19:41:59 +0530 2025</lastModifiedTime>
</containerLogInfo>
<containerLogInfo>
<fileName>prelaunch.out</fileName>
<fileSize>100</fileSize>
<lastModifiedTime>Wed Nov 05 19:41:59 +0530 2025</lastModifiedTime>

</containerLogInfo>
<containerLogInfo>
<fileName>stderr</fileName>
<fileSize>0</fileSize>
<lastModifiedTime>Wed Nov 05 19:41:59 +0530 2025</lastModifiedTime>
</containerLogInfo>
<logAggregationType>LOCAL</logAggregationType>
<containerId>container_id</containerId>
<nodeId>hostname:42923</nodeId>
</containerLogsInfo>
</containerLogsInfoes>`
So in getContainerLogFiles(), an additional
getJSONObject("containerLogsInfoes") has been added to ensure the XML response
is parsed properly
