> In UI2 for an application under the Logs tab, No container data available message is shown if the application attempt only submitted a single container (which is the AM container).
> The culprit of the issue is that the response from YARN is not consistent, because for a single container it looks like:
> {noformat}
> {
> "containerLogsInfo": {
> "containerLogInfo": [
> {
> "fileName": "prelaunch.out",
> "fileSize": "100",
> "lastModifiedTime": "Mon Nov 29 09:28:16 +0000 2021"
> },
> {
> "fileName": "directory.info",
> "fileSize": "2296",
> "lastModifiedTime": "Mon Nov 29 09:28:16 +0000 2021"
> },
> {
> "fileName": "stderr",
> "fileSize": "1722",
> "lastModifiedTime": "Mon Nov 29 09:28:28 +0000 2021"
> },
> {

> "fileName": "launch_container.sh",
> "fileSize": "5013",
> "lastModifiedTime": "Mon Nov 29 09:28:16 +0000 2021"
> }
> ],
> "logAggregationType": "AGGREGATED",
> "containerId": "container_1638174027957_0008_01_000001",
> "nodeId": "da175178c179:43977"
> }
> }{noformat}
> As for applications with multiple containers it looks like:
> {noformat}
> {
> "containerLogsInfo": [{
> ....
> }, { .... }]
> }{noformat}
> We can not change the response of the endpoint due to backward compatibility, therefore we need to make UI2 be able to handle both scenarios.
