When reviewing my code changes, please focus on:
Indexes utilize all the available IO devices. 
I added Zack because I want to him look at the changes related to the local 
resource repositories since he is familiar with that part of the code.

After the review, I'll merge this branch into:
/master

Sattam,

   There are multiple versions of some files (it's hard to track all deltas of a file). Can you send me two change lists (asterixdb and hyracks) using http://code.google.com/p/asterixdb/wiki/CodeReviewsWithRietveld?
   The specific command is:
   git cl upload origin/master -r buyingyi@gmail.com --send-mail -m "Code Review on xxx"

   It should be easy and automatic. Normally I just use 1-2 mins to send out that...  Can you let me know what issue you run into last time?
   Thanks!

Yingyi
