Hi Raja,
How does the HTTP request fail? Can you post the output of:
curl -v http://host:port/jobs
There are a couple of other ways to find out the port number. For example,
when
the YARN session is initially deployed, the url of the web ui is logged to
stdout:
https://github.com/apache/flink/blob/release-1.4/flink-yarn/src/main/java/org/apache/flink/yarn/cli/FlinkYarnSessionCli.java#L691
However, in a HA setup the JobManager may be restarted on a different host
in
case of a failure.
You can also get the port number from the JobManager logs:
https://github.com/apache/flink/blob/release-1.4/flink-runtime-web/src/main/java/org/apache/flink/runtime/webmonitor/utils/WebFrontendBootstrap.java#L129
Best,
Gary
