Todd Lipcon commented on HDFS-1073:

Hi Sanjay/Konstantin,

Thanks for the comments and questions. I didn't originally anticipate writing a design doc
inline, but you know, fingers started typing and a few pages later it was a very long JIRA
comment :) I'll do another rev to address your questions as well as flesh out the BN and Upgrade
bits, and upload it as an attachment here some time tomorrow.
