Jeff Jirsa commented on CASSANDRA-11714:
----------------------------------------
It seems like what you're really asking for is {{service cassandra restart}} to
call {{nodetool drain}} before it kills the daemon?
> shutdown script should wait more than 30 seconds before force kill

> I'm running with 3.0.6 and it appears that if I let it run for multiple days
> (ingesting a never-ending streaming data from Kafka), then the next time I'm
> restarting the JVM by "service cassandra restart", it will take 9 minutes to
> replay the commit log segments (the commitlog_total_space_in_mb is using the
> default 8GB and I observed close to 8GB commitlog segment files before the
> restart). Here is a fragment of the system.log showing how long it takes:

> If we could increase this 30-second to a higher wait time like 1 or 2 minutes
> we could make the startup delay much shorter.
> Keep in mind that we don't always have to wait for this long during the
> shutdown so we're not really losing anything with this improvement.
