As you have deleted the topic it looks like the consumer group is deleted, and you can remove the corresponding topic folders (from all nodes) and also the topic from zookeeper using the ZK CLI.

Re: what is the safe and best way to delete the kafka topic folders
just to be sure , so it will be safe to remove the topics use rm-rf as ( rm -rf hgpo.llo.prmt.processed-28 . rm -rf hgpo.llo.prmt.processed-28 and so on on all nodes ) ?

Re: what is the safe and best way to delete the kafka topic folders
another thing the topics are exist under /brokers/topics/* and not under /consumers/..../.. so in this case I gues we need to remove the topic as rmr /brokers/topics/hgpo.llo.prmt.processed , can you confirm this please
