-----------------------------------------
@Arun,
# Correct. To be even more explicit where Bigtop is coming from is -- building
a Bigdata management distribution/stack. To that end we have a hard goal of
harmonizing all dependencies between components in the distribution. IOW, if
component A happens to be part of the distribution all other components
depending on A have to depend on exact version of A that is part of Bigtop and
nothing else (that is why we try very hard to make sure that there's a single
copy of an A artifact(s) and all other components reference it in some way).
Hadoop is a good example of a component that is part of the distribution with
almost everything else depending on it (hence we use techniques ranging from
symbloic linking from lib to the actual Hadoop jars all the way to constructing
a classpath). We also have a soft goal of harmonizing dependencies that do NOT
come from the distribution itslef. IOW, if Bigtop components depend on a
non-Bigtop component foo, we would like to make sure that the version of foo is
common, but we don't really make sure that there just one copy of foo. log4j
artifacts are a good example.
# At this point we draw a very hard line at ASL. If a piece of software is not
covered by ASL, currently Bigtop will not be able to incorporate it. We try to
focus on ASF projects, but if a really interesting piece of software comes
along which is covered by ASL, but is not (yet?) part of the ASF -- we might
consider including it. Such was the case with Oozie, for example.
