Roman Shaposhnik updated HBASE-4209:
------------------------------------
Attachment: HBASE-4209.patch.txt
I'm attaching a sample patch that seems to be working well enough. The idea
behind it is to reference count the fsShutdownHooks that we have to run from
shutdown sequences of multiple RegionServers and only *really* run each when
the last registered regionserver shuts down. Please let me know what do you
think.
> The HBase hbase-daemon.sh SIGKILLs master when stopping it

> There's a bit of code in hbase-daemon.sh that makes HBase master being
> SIGKILLed when stopping it rather than trying SIGTERM (like it does for other
> daemons). When HBase is executed in a standalone mode (and the only daemon
> you need to run is master) that causes newly created tables to go missing as
> unflushed data is thrown out. If there was not a good reason to kill master
> with SIGKILL perhaps we can take that special case out and rely on SIGTERM.
