Reporter: Santosh Kumar Sahu
We were upgrading zookeeper.jar and zookeeper-jute.jar to 3.9.3 from 3.9.2, we
are facing *Cannot open channel to 1 at election address error* in all 3 pods.
Zookeeper configuration is same, only change is that zookeeper.jar and
zookeeper-jute.jar has changed to 3.9.3 version.
