Hello,
Any help would be apprecaited..
I have below setup for High Availability
NN1 (active) + ZKFC1
NN2 (standby) + ZKFC2
Then I kill the active node : kill -9 on NN1 process
NN2 stay on standby instead of changing to ACTIVE status
I see below error in the log of Failover Controller FC1 which runs on NN1
The error in the log is infinitely printing
