Re: Flink(1.12.2/scala 2.11) HA with Zk in kubernetes standalone mode deployment is not working

[Matthias Pohl <ma...@ververica.com>]

Hi Bhagi,
Thanks for reaching out to the Flink community. The error the UI is showing
is normal during an ongoing leader election. Additionally, the connection
refused warnings seem to be normal according to other mailing list
threads. Are you referring to the UI error as the issue you are facing?

What puzzles me a bit are the timestamps of your provided logs. They do not
seem to be fully aligned. Are there more logs that might indicate other
issues?

Matthias

PS: I'm gonna add the user mailing list as this issue should usually be
posted there.

Re: Flink(1.12.2/scala 2.11) HA with Zk in kubernetes standalone mode deployment is not working

[Till Rohrmann <tr...@apache.org>]

Somewhere the system retrieves the address x.x.x.x:43092 which cannot be
connected to. Can you check that this points towards a valid Flink process?
Maybe it is some leftover information in the ZooKeeper from a previous run?
Maybe you can check what's written in the Znodes for
/leader/resource_manager_lock.
You can also enable DEBUG logs which will tell you a bit more about what is
happening.

Cheers,
Till
