Hi all, I've found some solution for this issue. Problem is that with YARN ApplicationMaster URL we communicate with JobManager via proxy which is implemented on Jetty 6 (for Hadoop 2.6). So to use PATCH method we need to locate original JobManager URL. Using /jobmanager/config API we could get only host, but web.port is displayed as 0 (???) To find actual web port, we should parse YARN logs for jobmanager, where we can find something like this:
*INFO org.apache.flink.runtime.jobmaster.MiniDispatcherRestEndpoint - Rest endpoint listening at <host>:<port>.* Maybe someone knows less complicated way to find actual REST URL under YARN?
