Answer 1

The number of partitions can be retrieved from zookeeper-shell

Syntax: ls /brokers/topics//partitions

Below is the example:

root@zookeeper-01:/opt/kafka_2.11-2.0.0# bin/zookeeper-shell.sh zookeeper-01:2181
Connecting to zookeeper-01:2181
Welcome to ZooKeeper!

ls /brokers/topics/test/partitions
[0, 1, 2, 3, 4]
