StreamingUpdateSolrServer - thread exit timeout?

[Shawn Heisey <so...@elyograg.org>]

I've got a build system that uses SolrJ.  The currently running version 
uses CommonsHttpSolrServer for everything.  In the name of performance, 
I am writing a new version that uses CommonsHttpSolrServer for queries 
and StreamingUpdateSolr for updates.

One of the things that my program does is handle termination signals 
gracefully, with a static boolean value called runFlag that tells it 
that it should no longer be running.  Each of my threads watches that 
value and exits gracefully when runFlag is false.  This works perfectly 
fine if I use CHSS for everything, but when I use SUSS, it takes exactly 
60 seconds for the program to close.

Is there any way to get get the threads within SUSS objects to 
immediately exit without creating other issues?  Alternatively, if 
immediate isn't possible, the exit could take 1-2 seconds.  I could not 
find any kind of method in the API that closes down the object.

Thanks,
Shawn

I've got this in a standalone application with a main(), started from 
the commandline.  When I close it and it calls the shutdown hook, there 
is nothing from SolrJ logged to my log4j destination, stdout, or 
stderr.  I'm using SolrJ 3.5.0.

Is the memory leak you have mentioned still something I need to worry about?

Thanks,
Shawn

I've worked this out by getting rid of the SignalHandler stuff and 
implementing a shutdown hook.  Now I am only waiting for specific 
threads to exit, not all threads running in the VM.  A couple of 
bonuses: 1) No more compiler warnings.  2) Now I have a final message in 
the logfile saying the program is terminated.
