@Sriharsha Chintalapani - We had a call on this issue last month through hortonworks case ticket and you suggested to add this dependency along with other changes. I added it and it was working fine. However, removing this dependency also worked. Now from past 2 weeks, we came across the same exception twice. First time we resolved this issue by creating a new kafka topic and changing the consumer group name. Today, even that is not working. We keep getting the same exception regardless of curator jar being there or not. Any pointers ? ****************************************************************************************** Unable to get offset lags for kafka.
