Re: Shutdown Solr
In production systems I have done a three-stage technique. First, use the
container's standard shutdown tool. Tomcat, JBoss, Jetty all have their
own. Then, sleep for maybe 60 seconds. Then do kill, sleep more, then 'kill
-9'.

Thanks... "kill" should be / can be graceful; "kill -9" should kill
immediately... no any hang, whole point...

*No* application is graceful for "kill -9". The whole point of "kill
-9" is that it's uncatchable.

*No* application is graceful for "kill -9". The whole point of "kill
-9" is that it's uncatchable.

RE: Shutdown Solr
Most probably Ctrl-C is graceful for Tomcat, and kill -9 too... Tomcat is
smart... I prefer "/etc/init.d/my_tomcat" wrapper around catalina.sh ("su
tomcat", /var/lock etc...) - ok then, Graceful Shutdown depends on how you
started Tomcat.
RE: Shutdown Solr
SolrDispatchFilter has it:
public void destroy() {
if (cores != null) {
cores.shutdown();
cores = null;
}
}
It should gracefully shutdown all background threads (used by Lucene
index-merge etc)
Tomcat: catalina.sh stop, shutdown.sh, etc.;
Ctrl-C is not graceful

catalina.sh stop
But SolrServlet catches everything and forgets to implement destroy()!
I am absolutely unsure about Ctrl-C and even have many concerns regarding
catalina.sh stop... J2EE/JEE does not specify any support for threads
outside than container-managed...
I hope SolrServlet closes Lucene index (and other resources) and everything
follows Servlet specs... but I can't find dummies' method _"destroy()"_ in
SolrServlet!!! It shold gracefully close Lucene index and other resources.
WHY?

it catches the kill signal and shuts down as it should, I guess :) because
it writes stuff to the log after pressing ^c
