I am issuing a GET call to list running jobs on Flink Session. Another quick question, is there a way to check the port on which my Flink YARN Session is exposing REST API ?
Because, I could figure out on UI either in YARN Resource Manager / Flink Web UI of YARN Session the port number I received from Yarn Client using the command “yarn application -list” Thanks a lot.

If it is not a GET request, it could be that you are suffering from this bug: https://issues.apache.org/jira/browse/YARN-2031 In my case the tracking url shown on the resource manager ui is indeed one that targets the YARN proxy, i.e., POST/DELETE/PUT requests are not supported. However, the tracking url obtained from the YARN cli directly refers to the jobmanager.

As you informed, I am able to query REST API, by capturing the tracking-url, I get by using the command “yarn application -list” But, however as I observe in the YARN Resource manager UI, I am not able to query using the tracking url I am observing in YARN Resource Manager. Not sure, If the Hadoop environment I am on, is using some proxies or etc. Do you have any thoughts on why this is happening different in YARN command line Vs YARN Resource Manager ? Thanks a lot again. Regards, Raja.

You can retrieve the URL by using the YARN client: yarn application -list In the output, the rightmost column shows the URL, e.g., Application-Id ... Tracking-URL application_1517585200464_0001 ... http://ip-172-31-40-165.eu-central-1.compute.internal:38045 You can also find the tracking URL in the Web UI of the YARN resource manager.

While I was able to trigger applications and run them. I wish to find the URL of REST API for the Flink YARN Sesssion I launched. Can someone please help me point out on how to find the REST API Url for the Flink on YARN? Thanks a lot. Regards, Raja.
