Nigel Daley commented on HADOOP-1831:
-------------------------------------

Hmm, there seems to a problem on Solaris with UNIXProcess.forkAndExec which 
JUnit must use:
http://hudson.gotdns.com/wiki/display/HUDSON/Solaris+Issue+6276483

I applied the suggested workaround here:
http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=6276483
in jre/lib/security/java.security file and restarted Hudson last week. This has 
fixed Hadoop-Patch-Admin build hanging when it was gettting going.  I wonder if 
it will fix this problem too.  If no tests hang over the next week, I'll close 
this issue.

> Hudson should kill long running tests. (I believe it is supposed to but 
> doesn't quite seem to do the job if the test is really hung up).
> It would be nice if, when the timer goes off, Hudson did a {code}kill 
> -QUIT{code} (to try to get a thread dump) and then followed that with a 
> {code}kill -9{code}
> (See the section "Killing a hung test" at
