-------------------------------------
Hi Neha,
What is the status of fixing this issue? This issue happens on every run. I
have seen, if I use: num.replica.fetchers=1, then sometimes this issue goes
away however I see other problem of leadership changes very often even when all
brokers are running.
If I set: num.replica.fetchers=4, then I can reproduce this issue on every run.
Please let me or Evan (from sarama) know if you need any help to fix this.
