+1, looks like the standard ASF process

That said
  -the JIRA/hudson review process isn't so common on other projects, 
where it's usually lazy post-commit-veto. That doesn't mean the Hadoop 
process is bad, only that you may want to say "the process used for 
getting code in is stricter than many existing ASF processes due to the 
value of data stored in Hadoop clusters. The exact process for 
committing code will be defined by the PMC and voted on" -then you can 
propose/vote the existing process, but have the ability to change things 
without reconstituting.

-the proposal for big changes that was discussed  may also be something 
that this would cover

-Vetoes can kill a project. It's the situation you don't want to get, 
where someone starts -1 rejecting everything. It might be good to lay 
out what the escalation process is for resolving vetoes that cannot be 
resolved -is there a way to raise with the PMC, etc.?
