+1 on graduating .205 as 1.0. It is a very mature and widely used version of Hadoop and really has a significant bang for a buck!
It seems that making 0.22 to be 2.0 has a lot of sense because its coming release carries a number of significant changes qualifying it to be a major release. .23 seems to be a good candidate for 3.0 for exactly the same reasons with MR2 framework and all. Seems like a great time for the move! Cos On Mon, Nov 14, 2011 at 02:11PM, Arun C Murthy wrote: > Folks, > > Apache Hadoop has come a long way since our humble beginnings.
