Use storm to process the topic data in kafka in real time, and want to view the consumption of the topic

How to implement: Enter the client interface of zookeeper: ./zkCli.sh-----

Check out the catalog:

The code level of this response: ------- Here is the consumer group corresponding to the topic, and its storage path is under zookeeper

String zkRoot = "/stormkafka" ; 
         // equivalent to the consumer group 
//         String id = "hbase_data2"; 
        String id = "hbase_data6" ;
        BrokerHosts brokerHosts = new ZkHosts(zks);
        SpoutConfig spoutConf = new SpoutConfig(brokerHosts, topic, zkRoot, id)；

 Next, check the corresponding situation in the consumer group directory:

 

You can see that this is the partition directory of the topic

For this, you can view the consumption of the topic
