kafka + description of the leaders and replications one of the leader not exists

kafka + description of the leaders and replications one of the leader not exists

hi all

we have three kafka brokers ( 101 , 102 ,103 )

when we run the following command

kafka-topics.sh --zookeeper 10.231.23.45:2181 –describe

we see the description of the leaders and replications

but what is wrong here is we see only two leaders for each topic

in our case the topic name - MLK_PLW_QA , but the same situation is on all the topics

Topic:MLK_PLW_QA PartitionCount:100ReplicationFactor:3Configs:retention.bytes=9239504949
Topic: MLK_PLW_QA Partition: 0Leader: 102Replicas: 102,101,103Isr: 101,102,103

I must to say that this situation not appears before couple days , and we see all leaders 101 , 102 , 103 ( from kafka-topics.sh --zookeeper 10.231.23.45:2181 –describe )

what are the reasons that broker id - 103 not appears as leader ?

note - all kafka brokers services are running
