How do I investigate checkpoints failures

Hello,

I have a cluster with multiple jobs running on it. One of the jobs has
checkpoints constantly failing

How do I investigate it?

Thank you,

Hi Alex,

First thing to do in such cases is to analyze logs for jobmanager and
taskmanagers and look for exceptions there.

The cause for latest failed checkpoint says the checkpoint expired. You
can try increasing the checkpoint timeout (you can check more
configuration options for checkpoints here [1]).

Best,

Dawid
