Subject Re: [VOTE] Release candidate
Date Thu, 05 May 2011 06:21:08 GMT
I'm not going to cast a vote, but I'm concerned about this for the same reasons Eli brought
up -- in particular, compatibility with 0.22. I'm an author of several patches that have gone
into 0.21 and trunk, only to stay on hiatus for 2 years because the project hasn't made a
stable release since 0.20. (Today, many of these patches are being used through CDH, which
is great, but it would be nice to see them in an Apache release too.) This push of features
into 0.20.203 makes a widely used 0.22 seem even more distant. Can we at least get a confirmation
that these changes will be included in 0.22, as well as a timeline?

To support a vibrant developer community, Apache Hadoop should not just be a mechanism for
Yahoo and Cloudera to publish patches. It should include a well-defined process for smaller
third-party contributors to push changes that will make it into a stable release within a
reasonable time horizon. The lack of such a process has been a major cause for the slowdown
in the project in my perspective.
