Answer 1

Go to your kafka/bin directory.

Then run this:

./kafka-topics.sh --describe --zookeeper localhost:2181 --topic topic_name

You should see what you need under PartitionCount.

Topic:topic_name        PartitionCount:5        ReplicationFactor:1     Configs:
        Topic: topic_name       Partition: 0    Leader: 1001    Replicas: 1001  Isr: 1001
        Topic: topic_name       Partition: 1    Leader: 1001    Replicas: 1001  Isr: 1001
        Topic: topic_name       Partition: 2    Leader: 1001    Replicas: 1001  Isr: 1001
        Topic: topic_name       Partition: 3    Leader: 1001    Replicas: 1001  Isr: 1001
        Topic: topic_name       Partition: 4    Leader: 1001    Replicas: 1001  Isr: 1001
