Subject Re: [ANNOUNCEMENT] Apache Hadoop 0.22.0 release
Date Wed, 14 Dec 2011 07:28:38 GMT
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
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.
