Ignite Shutdown Hook

[hemanta]

Hi,

I am starting Ignite as standalone program embedded in my java application via Spring configuration. It works great however my application stucks and never finishes. I have added some shutdown hooks but they are never called. I think this is because Ignite is running in main thread and stopping jvm to exit.

I want jvm to stop Ignite and exit gracefully but this is not what I am seeing. Any suggestions? Thank you.

Hi,

I'm not sure I understand the problem... Where is the application stuck?
Did you look at thread dump?

Thank you for your reply. It is stuck at Ignite.
If in last line of public static void main() I add code to stop Ignite then everything works fine. But I have so many stand alone classes (public static void main) that run as a part of upgrade that I can not add Ignition.stop() in all of them. So, I was looking at option of shutdown hook which is not working with Ignite.

I see lots of IgniteThread in threaddump.
