> Improve Kafka service check to check for under-replicated partitions

> Key: AMBARI-24203
> URL: https://issues.apache.org/jira/browse/AMBARI-24203
> Project: Ambari
> Issue Type: Bug
> Components: stacks
> Affects Versions: 2.7.0
> Reporter: Yolanda M. Davis
> Assignee: Yolanda M. Davis
> Priority: Major
> Labels: pull-request-available
> Fix For: 2.7.0
>
>
> 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}
