----------------------------------
Summary: Document how to use kafka-reassign-partitions.sh to
change log dirs for a partition
Key: KAFKA-9389
URL: https://issues.apache.org/jira/browse/KAFKA-9389
Project: Kafka
Issue Type: Improvement
Reporter: James Cheng
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.
