Thanks for your answer. Our dataset is not huge may be 10-15 TB of data at the moment. or over the period of 2-3 yrs grow to 15-20 TB at max. We intent to build this datalake in cloud but not using cloud provider platform as they don't provide data gov and lineage tracking.. our data set is mostly going to be unstructured..

I assume you are referring to multi-data lake in your organization? or you are referring to processing the same feed in same datalake based on different kind of requirement? Why not storing the data in same datalake? as you mentioned we got multiple production environments..

Can some one point me in right direction of how to setup KAFKA cluster on HDP platform. To setup kafka clusters usually we add broker.id=1,2,3... but hortonworks doesn't provide this option to add in thr.. Issue: is when i try to create kafka topics i am able to create with 2,3 partitions and replicas 2,3.. but starting consumer and producer start throwing exception unknown topic or partition. My guess is it;s due to kafka HA configuration..
