I'm about to push the broken apart hadoop-0.20-security into hadoop-0.20-security-patches. It is 863 patches for the main branch. There are two release branches off of it that have a few patches each. The version that Arun pushed originally is 0.20.202.X and there is a newer release branch that is 0.20.203.X. The 202 and 203 branches have a few patches each. For now, I propose calling the branches:
branch-0.20-security branch-0.20-security-202 branch-0.20-security-203 -- Owen
