Hi Guys,
I found lots of warning log in broker's server.log, any idea you have ? my
major concern why `failed due to null` will happen ? can I see it zookeeper
not available at that moment ?
WARNING log :
[2018-07-20 20:47:34,868] WARN Conditional update of path
/brokers/topics/HeartBeat/partitions/0/state with data
{"controller_epoch":4,"leader":1005,"version":1,"leader_epoch":6,"isr":[1005]}
and expected version 10 failed due to null (kafka.utils.ZkUtils)
