version numbers

Ah, Hadoop-land, where version numbers signify much more then a version:

  • 1.0.X – current stable version, 1.0 release
  • 1.1.X – current beta version, 1.1 release
  • 0.23.X – current alpha version, MR2
  • 0.22.X – does not include security
  • 0.20.203.X – legacy stable version
  • 0.20.X – legacy version

0.2 is legacy, 0.23 is alpha, 0.22 is (legacy?) without security, 1.0 is stable, and 1.1 is beta.
