Hi, Ansanth I don't see any error logs on the server side, so it's hard to tell what the specific problem is. From the current log, there are two things to try first:
1. From the client's log, it is a 5-minute timeout, so you can telnet 127.0.0.1:8086 to see if there is a problem with the local network 2. From the log on the server side, there is no job submission at all. You can try to submit the wordcount example again when submitting the pulsar example fails. So as to rule out whether the session cluster is inherently problematic.
