Roman and Cos, thanks by the explanations.
I can use with no problems the release 0.3.0 to build Hadoop-1.1.x RPMs,
but I was just curios to know the reason of that change between releases
0.3.0 and 0.4.0.
So, if I understand well, the reason was a consensus of Bigtop community
that Hadoop-2.x is a more interesting choice than Hadoop-1.1.x for now.
That's OK!!
Actually, we are working with Hadoop-2.x (and we, at least me, prefer
this one) but we still have some work on branch 1.1.x, that obligate us
to build RPMs for this release. So, our environment has bigtop-0.5.0 to
build all other components, and 0.3.0 to build Hadoop-1.1.x.
Thanks again guys, and I'm going to start contribute with the project
and bore you guys with more questions and discussions.
Regards, Paulo.

Hadoop 1.x based stacks are destined to be supported in 0.3.x line of BigTop

JIRAs on that and you're very welcome to help with it!
To add to what Cos said: Bigtop is totally community and consensus driven.
If there's a bunch of folks who'd be interested in a Bigdata management
distribution based on Hadoop 1.X -- they are more than welcome to
congregate around branch-0.3 and do periodic releases from there.
Personally, I believe that Hadoop's 2.X HDFS is a better choice at this point
then Hadoop 1.X's. MapReduce is a different matter -- arguably it is still
in alpha stage but there seems to be a lot of interest in investing into
stabilization of it. Hence most of the folks involved in Bigtop so far feel
like overall Hadoop 2.X may be a more interesting platform. That's why
you see Bigtop releases based on it.
Hope this helps.
Thanks,
Roman.
P.S. Of course, in the ideal world, HDFS and YARN and frameworks like
Mapreduce would be separate projects and you'd be able to mix and
match them freely. Alas -- we're not quite there yet :-(
