shutdownHookfor shutdown method of executor plugin. This will ensure that shutdown method will be called always.Why are the changes needed?
Whenever executors are not going down gracefully, i.e getting killed due to idle time or getting killed forcefully, shutdown method of executors plugin is not getting called. Shutdown method can be used to release any resources that plugin has acquired during its initialisation. So its important to make sure that every time a executor goes down shutdown method of plugin gets called.
Does this PR introduce any user-facing change?
No.
