It is stated in a few places on the website that 0.21 isn't stable: http://hadoop.apache.org/common/releases.html#23+August%2C+2010%3A+release+0.21.0+available "It has not undergone testing at scale and should not be considered stable or suitable for production." ... and ... http://hadoop.apache.org/common/releases.html#Download "0.21.X - unstable, unsupported, does not include security" and it isn't in the stable directory on the apache download mirrors.
