[Jimit Shah <ji...@gmail.com>]

Are there startup and shutdown hooks for storm worker nodes that I could
use?

Thanks,
Jimit

I don’t know of worker hooks, but shouldn’t be interpreted of them not existing.

Bolts have prepare and cleanup methods that could probably be hacked to implement worker lifecycle hooks.

The jvm has shutdown hooks: http://docs.oracle.com/javase/7/docs/api/java/lang/Runtime.html#addShutdownHook(java.lang.Thread)
