Todd Lipcon updated HDFS-1073:
------------------------------
Attachment: hdfs1073.pdf
Here's a more fleshed out design document, including BN operation, upgrade, and
some of the future direction design sketches. I tried to address the questions
above - I'll take another pass through it tomorrow to see if I missed any of
the comments.
I'll also work on adding a section to compare and contrast the two alternatives
that we're still debating - ie file names with transaction IDs vs file names
with sequential numbering.
Thanks for all the feedback!
