> During Ambari Rolling Upgrade, we invoke Kafka Service check to ensure that Kafka is healthy. The current implementation only does basic topic creation/deletion. We need to extend the implementation to check for number of under-replicated partitions.
> We have this support in kafka-topics.sh script which is already used in the kafka service check script. We need to extend above script to call below command
> {noformat}
> sh kafka-topics.sh --describe --zookeeper localhost:2181 --under-replicated-partitions
> {noformat}
> If the command output is empty, then there are no under replicated partotions.
> If the output contains "Topic:" string, then there are some under replicated partitions, we can fail the service check.
> {noformat}
> sh kafka-topics.sh --describe --zookeeper localhost:2181 --under-replicated-partitions
>  Topic: TEST Partition: 0 Leader: 1 Replicas: 1,2 Isr: 1
>  Topic: TEST Partition: 1 Leader: 1 Replicas: 2,1 Isr: 1{noformat}
