We did discuss this as a long term goal when bigtop formed; As a distro developer who has no option other than to use OpenJDK for the majority of my work I would like to help resolve these issues - I think its important for the long term health of Hadoop and OpenJDK. I also know quite a few of the OpenJDK developers and I know they are focussed on making OpenJDK great so it then just comes down to user choice rather that a complete no-go (which incidentally I don't think it is ATM). I think the other thing that I don't see much movement on is the switch to Java7 - technically this should make things much easier as OpenJDK 7 and Oracle Java 7 are pretty much the same thing. Fedora are already working on removing OpenJDK6 (see [0]) and I expect to start doing the same in Ubuntu/Debian in the next few months... Most OpenJDK development is now also focussed on 7 not 6....
