Roman Shaposhnik commented on BIGTOP-316:
-----------------------------------------
Sure. Just keep in mind that this JIRA only applies to Hadoop post 0.21.
Rationale: it seems that there's a growing interest in mixing and matching
individual subprojects of Hadoop:
* running mixed version of HDFS and mapreduce framework (e.g. 1.0 mapreduce
on top of 0.22/0.23 HDFS)
* substituting mapreduce with alternative frameworks such as MPI (only
available in .23)
* substituting HDFS with alternative implementations of distributed
filesystems
* using standlaone HDFS+HBase clusters
On top of that, there's an increased level of interest from deployment
perspective to have a precise
control on what bits end up being installed on every node with a cluster.
Implementing the fix for this JIRA will pave the way for a much more flexible
ways of utilizing individual
sub-projects of Hadoop.
Finally, from the standpoint of packaging guidelines of every major
distribution it is highly desirable
to split loosely coupled components into individual packages. Debian developers
would go as far
as insisting that every jar file must be its own package.
Implementing the fix for this JIRA will pave the way for Bigtop to be used as a
basis for Hadoop
packaging in major Linux distributions.
Please let us know if this raises any concerns on your side.
