Unit tests + new wiki page

[Alex Loddengaard <al...@google.com>]

I think I know the answer to this question, but I'll ask just for a sanity
check: should all unit tests pass in a fresh trunk build?

While I'm here, FYI: I'm working on an IDE agnostic development environment
HOWTO on the wiki.  Take a look and contribute what you can:

<http://wiki.apache.org/hadoop/HowToSetupYourDevelopmentEnvironment>

I'm in the middle of getting a local build compiled and running, so I'm
documenting my process in hopes of helping other people down the road.

Thanks.

I'll qualify Owen's "yes" with "yes provided your system is close enough 
to the supported systems".
-if your DNS or /etc/hosts is a mess; don't be surprised when things fail
-if you are running JRocket JVM, you need to switch to a different 
log4j.properties to avoid deadlocks in the JVM.
-there may be other installation-specific issues which you get to debug.

-JPackage ant distros don't ship with a lot of ant; usually better to 
install a version of apache.org, or, if you do want rpm/deb managed ant 
to ask for ant-* to get the extra bits (which is all designed to avoid a 
cycle in the dependency graph), and clearly junit too.

-"ant diagnostics" is your tool for auditing Ant installations.

-it might be best to put the runtime errors into the existing 
troubleshooting page

Yes. If code gets checked in that breaks the regressions, it is a bug and
should be fixed.
