Jason Altekruse commented on DRILL-996:
---------------------------------------
We need to discuss this more before implementing it if it is really needed.
While there are a few places in the pom files where we are declaring the
version numbers as maven properties/variables, these have been used to removed
redundancy, not to enable custom versions to the passed on the command line. We
have not historically supported multiple versions of any our dependencies at
the same time. If we need to start doing this, I think all of the supported
versions need to be included in a multi-phase build where all unit tests will
be run against each configuration.
> Build - allow other versions of Hadoop to be specified on command-line

> Right now, in order to change the version of Hadoop that Drill is built
> against, you have to edit the POM. However, for automated build systems that
> build Drill against a variety of possible Hadoop versions, it would be much
> cleaner to be able to specify it on the command-line.
