I grabbed Hadoop: The Definitive Guide
Tomcat: The definitive Guide 2nd ed (this one I have access to via ACM membership but those rotate out potentially so eh)
Head first Statistics (my math skills are beyond rusty, and the head first books tend to be good.
However either due to overload or something, while I was able to place my order, the books are not showing up in my available list yet. Figure I'll give them until tomorrow then throw an email at them asking what's wrong.
