Description
We're trying to upgrade NiFi from 1.19 to 1.20. It is deployed in cluster mode.
pods are in crash loop backoff.
nifi-0 3/3 Running 0 20h nifi-1 3/3 Running 0 20h nifi-2 2/3 CrashLoopBackOff 164 (2m24s ago) 17h
we have observed that the upgrade starts from pod nifi-2 then nifi-1 and later 0
we're getting this exception on checking pod nifi-2.
