Flink UI not responding on Yarn + Flink

[samar kumar <sa...@gmail.com>]

Hi Users,
 I am currently trying to run flink with yarn. I have written a program
which will launch flink jobs on yarn . It works perfectly fine with local
yarn cluster . When I run it on a remote yarn cluster it does not work as
expected. As I am reading and writing data from kafka , I do not see any
data on the destination kafka topic. The yarn log goes print the
transformation I want to apply. I am not able to debug the issue because
there is no error in the yarn logs. Also the flink application UI seem to
be blank , and does not give the usual flink job list. Please help me debug
and fix the issue.

Running Flink 1.3.2 with yarn 2.6
Thanks,
Samar

Hi Samar,

Can you share the JobManager and TaskManager logs returned by:

  yarn logs -applicationId <ID>?

Is your browser rendering a blank page, or does the HTTP request not finish?
Can you show the output of one of the following commands:

  curl -v http://host:port
  curl -v http://host:port/jobs

Best,
Gary
