--------------------------------

[~chenshangan521@163.com], could you write up a high level description of what the new tool does? Also, for major changes, we require people to submit a KIP proposal (https://cwiki.apache.org/confluence/display/KAFKA/Kafka+Improvement+Proposals).

> The default partition assignment algorithm can work well in a static kafka cluster(number of brokers seldom change). Actually, in production env, number of brokers is always increasing according to the business data. When new brokers added to the cluster, it's better to provide a tool that can help to move existing data to new brokers. Currently, users need to choose topic or partitions manually and use the Reassign Partitions Tool (kafka-reassign-partitions.sh) to achieve the goal. It's a time-consuming task when there's a lot of topics in the cluster.
