Steve Loughran commented on YARN-5570:
--------------------------------------
YARN-679 tries to be a single entry point for anything that implements
Service/subclasses AbstractService & adds extra support for an interface to
take command line arguments.
It does double-exit escalation: first control-C triggers System.exit() and a
shutdown with the hooks running; a second SIGINT triggers escalation and a hard
System.halt. This addresses the issue that when IPC clients block in the
retry/attempt cycle, they can deadlock on the shutdown code
> NodeManager blocks kill attempts during startup if ResourceManager is down

> Found while testing a 2.7.3 RC:
> {quote}
> * If you start the NodeManager and not the RM, the NM has a handler for
> SIGTERM and SIGINT that blocked my Ctrl-C and kill attempts during startup. I
> had to kill -9 it.

> [[email protected]] tells me that this is potentially addressed by YARN-679,
> though that's a large patch.
