Patrick Hunt commented on ZOOKEEPER-2387:
-----------------------------------------
I'm -1 this patch or any patch that implements such a behavior.
The current approach of doing a "kill -9" is as by design. We want to (and have
done so from day 1 of ZK) make the non-graceful shutdown of the service the
default. That way we force ourselves to handle all the corner cases rather than
just seeing those corner cases when someone experiences a non-graceful shutdown
because of an unexpected failure in production. Many systems use the "graceful"
approach and run into problems as a result - they don't see the corner cases in
every day and only face them in a much smaller number of scenarios when
something else bad is happening.
"kill -9" is a feature, not a bug. ;-)
