YeLiang created KAFKA-7880:
------------------------------
Summary: 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
Fix For: 2.1.1
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
