Migrating from standalone kafka to bundled CDH kafka

Migrating from standalone kafka to bundled CDH kafka

New Contributor

We are running kafka_2.10- which was installed prior to the inclusion of kafka in CDH.  Now that kafka  is included (

we would like to deploy to our hosts.  We currently have 3 hosts running kafka and have 3 more to add.  I was thinking I could deploy the kafka parcels

to the 3 new hosts and get them running but I don't know if the installation will overwrite any znodes etc.  We are currently using ZK for offsets and

I don't know if the CDH install will see that and just add more hosts etc.  What is the recommended way to move from the standalone to the included

CDH kafka while still preserving our topics and partitions?
