Right now I believe the version in CDH3b3 is more stable than the 0.90rc. This is from the testing I've done in-house with our clusters - assignment issues cropped up in 0.90 which I haven't seen in 0.89.20100924. The next rc or 0.90.0 should be better, and then we'll update CDH as well. > I'm not sure we forgo support for our ops team just because we do that.
