Description

KIP-113 introduced support for moving replicas between log directories. As part of it, support was added to kafka-reassign-partitions.sh so that users can move replicas between log directories. Specifically, when you call "kafka-reassign-partitions.sh --topics-to-move-json-file topics-to-move.json", you can specify a "log_dirs" key in the topics-to-move.json file, and kafka-reassign-partitions.sh will then move those replicas to those directories.

 

However, when working on that KIP, we didn't update the docs on kafka.apache.org to describe how to use the new functionality. We should add documentation on that.

 

I haven't used it before, but whoever works on this Jira can probably figure it out by experimentation with kafka-reassign-partitions.sh, or by reading KIP-113 page or the associated JIRAs.
