> KafkaConnect should standardize worker thread name
> --------------------------------------------------
>
> Key: KAFKA-7880
> URL: https://issues.apache.org/jira/browse/KAFKA-7880
> Project: Kafka
> Issue Type: Improvement
> Components: KafkaConnect
> Affects Versions: 2.1.0
> Reporter: YeLiang
> Assignee: YeLiang
> Priority: Minor
>
> KafkaConnect will create a WorkerTask for tasks assigned to it and then
> submit tasks to a thread pool.
> However,the
> [Worker|https://github.com/apache/kafka/blob/2.1.0/connect/runtime/src/main/java/org/apache/kafka/connect/runtime/Worker.java]
> class initializes its thread pool using a default ThreadFactory.So the
> thread name will have a pattern pool-[0-9]\-thread\-[0-9].
> When we are running KafkaConnect and find that one of the task thread is
> under high CPU usage, it is difficult for us to find out which task is under
> high load becasue when we print out the stack of KafkaConnect, we can only
> see a list of threads name pool-[0-9]\-thread\-[0-9] even if we can know the
> exact pid of the high CPU usage thread
> If worker threads name will be named like connectorName-taskId, it will be
> very helpful
