Good question, Jie.

In the voting thread for Hadoop 0.22.0 I provided some information on
what was done for 0.22.0 and where it stands with respect to its
stability. If you follow this thread
http://s.apache.org/COC
the one with the subject line "[VOTE] Release hadoop-0.22.0-rc0" you
may find some useful details.

Based on everything I now about the release, based on the testing I
and people I worked and/or collaborated with, based on that 0.21.0 was
its alpha predecessor and current stable is 0.20.203.X, I think it
leaves 0.22.0 in beta stage. But the point is not what I think.

The important thing is what you and everybody else think once you try
and verify it. Hadoop is intended for different platforms and use
cases. With as much testing as one can do the only guarantee of
stability in your particular environment and with your own big data is
to try it, confirm the results, file, or fix bugs. Contributions to
the project as a user or a developer are equally welcome.

Thanks,

Perhaps I missed it in another thread but does this become 2.0 then?

Yes this has been discussed in one of the threads about Hadoop 1.0.
The idea was to rename .20 to 1; .22 to 2 and .23 to 3. So it's a
matter of reaching a consensus via voting.
