-----------------------------------
Summary: Add a thread dump REST API
Key: FLINK-17485
URL: https://issues.apache.org/jira/browse/FLINK-17485
Project: Flink
Issue Type: Improvement
Components: Runtime / REST
Reporter: Xingxing Di
My team build a streaming computing platform based on flink in our company
internal.
As jobs and users grow, we spent lot's of time to help user with
troubleshooting.
Currently we must logon the server which running task manager, find the right
process through netstat -anp| grep "the flink data port", then run jstack
command.
We think it will be very convenient if flink provide a REST API for thread
dumping, with web UI support event better.
So we want to know:
* If community is already working on this
* Will this be a appropriate feature (add a REST API to dump threads), because
on the other hand, thread dump may be "expensive"
