Error in fetch kafka.server.ReplicaFetcherThread$FetchRequest@64cc68c3 (kafka.server.ReplicaFetcherThread)

New Contributor

Hi All, We are facing the following issue in one of our clusters. This issue is coming intermittently. We have HDP 2.6.1 version(kafka

However, when we restart Kafka ,the issue goes away and reappears intermittently later.

Note : We have not upgraded our cluster. This is a fresh installation.

We also looked at the network status, however it was not showing any lag/fluctuations.

I believe this should be due to network related issues. You may want to cross check if things are ok from network site and there are no packet drops when this issue occurs.

Thanks a lot Sandeep. I will cross check and validate if there are any network issues.
