I believe there are plans for an 0.18.4 release eventually, though a new
feature like a new DFS is unlikely to be included. I would concentrate on
integrating against trunk rather than a past release. If trunk is
inconvenient since it's a moving target, you could integrate against
branch-20. While a lot of people are currently using 0.18, I anticipate that
most users will be switching over to 0.20 in the next couple of months.

Single JIRA should be fine - just post multiple patches.

In general you should be aware that you should integrate as a new project in
the contrib/ dir. If all goes well you shouldn't need to make any patches
that touch Hadoop itself.
