a few admin guide notes
A couple notes on the current admin guide.
1) There's a reference to an internal Yahoo! hudson under "Chukwa
Binary". Probably should be excised.
2) Do I need to download tomcat and stick it in /opt? If not, how
does HICC get ahold of it?
3) What happens if I add multiple databases to jdbc.conf ?
4) Do we need to give the whole my.cnf in the admin guide? It breaks
up the flow of the document. Can't we just say, "look in
CHUKWA/opt/..."?
5) We still have bin/start-agents.sh and start-collectors.sh Do these
still work? Are they being maintained? Should they be documented?

The hard code version number should be replaced. This was placed in the
script without much thinking. I filed CHUKWA-196 to keep track of required
changes.

Awesome.
Also:
1) The tomcat/hicc set-up should probably be documented.
2) Is there a reason we're hardcoding a Tomcat version in
bin/start-data-processors.sh?

This should be renamed.

Yes, download tomcat and extract to opt, and you should copy hicc.war to
apache-tomcat/webapps, then copy descriptors, views from
chukwa/opt/apache-tomcat/webapps/hicc to
Chukwa/var directory.
I will ask Corinne to include this in the documentation.

jdbc.conf supports multiple databases with this syntax:
<cluster>=jdbc:mysql://<host>:<port>/database?user=<user>&password=<password

If the data processor node contains multi-line jdbc.onf, it will run
aggregation and down samples on the defined databases.

+1 on this improvement. CHUKWA-191 filed.

Both of those should work, but we are not using them in Yahoo nor testing
them.
