Thank you Aljoscha. 

I am able to Query state when I use the hostname of Job Manager instead of its IP Address. But I couldn't understand why it is not working if I give IP address.

Hi,

Is my-machine:52650 the correct address for the JobManager running in YARN? Also, Queryable State in Flink 1.3.2 is not easy to get to work when you use YARN with HA mode.

Best,

Aljoscha

Hi,

I am running a Flink Job which uses the Queryable State feature of Apache Flink(1.3.2). I was able to do that in local mode. When I try to do that in Cluster mode (Yarn Session), I am getting Actor not found Exception. 

Please help me to understand what is missing.
