Apache Hadoop or CDH?

[Owen O'Malley <om...@apache.org>]

Hi all,

   I noticed that Roman filed a bug to explicitly support CDH (BIGTOP-20). Does Bigtop intend to allow support any other proprietary forks of Hadoop or just CDH? (eg. EMC's or Brisk, etc) Does it support Hadoop and CDH or just CDH? The project proposal said it was for Hadoop, which is what comes from Apache.

  This is important. Obviously, if Bigtop's scope is just CDH it is much less interesting to me. On the other hand, for an Apache project to be exclusively focused on one company's fork of Hadoop seems wrong.

Hey Owen,

Bigtop's scope is Apache releases. Roman pasted the description of
DISTRO-54 into BIGTOP-20 verbatim, the intent was not to support CDH
in Bigtop. Since the current Bigtop source is based on CDH the same
bug applies which is why he's created the jira. I updated the
description to be more clear.

Thanks,
Eli

In case this is not obvious to others, BigTop has been working only
against Apache releases since day one.
Bigtop does not have any mechanism to deal with anything else than bare
source and pristine releases (although one could use the mechanisms
provided by rpm/deb).

The URLs used to pull releases are defined in this file:
https://github.com/apache/bigtop/blob/trunk/bigtop.mk
They all point to bare pristine source releases. Please, don't hesitate
to open tickets if you see anything wrong.

By what has been defined during the incubation process, we also restrict
ourselves from patching anything. So each release has to be rebuildable
out of the box or we will not be able to include it in BigTop.

Thanks,
Bruno
