I tend to interpret Hadoop 0.21 and Pig 0.9 as "Hadoop has had 21 releases" and "Pig has had 9 releases" respectively. In keeping with that, Pig version numbers that trail Hadoop seem logically consistent because Pig, in practice, primarily works off Hadoop (though it can do local mode, drive non Hadoop backends etc.).
So, Hadoop at 0.21 and Pig at 0.10 seems right. Of course, I may be missing a lot of things here with regard to how Apache projects works.

One thing we need to decide is what name/number to give to the next release: Pig 0.10 or Pig 1.0. I believe that we are ready to declare 1.0. Here are my reasons: (1) We are mature enough and produce good quality releases (2) Our interface no longer change in major ways (3) We have a growing user community and we want the newcomers to know that our releases are stable (4) If the next release is 0.10 and we decide that we should switch on the following release going from 0.10 to 1.0 will generate a lot of confusion. I wanted to start this conversation and see what others think before deciding if it is worth while to call a vote. Olga
