Change subject: IMPALA-4277: allow overriding of Hive/Hadoop versions/locations

Patch Set 2:

File bin/

Line 145: export CDH_MAJOR_VERSION=5
> Bump?
There was a separate cleanup effort to remove CDH references from Apache Impala so I think
this will be going away soon.

Line 146: export HADOOP_LZO="${HADOOP_LZO-$IMPALA_HOME/../hadoop-lzo}"
> How is this assigned?
This either comes from the environment (e.g. build script or .bashrc), otherwise it assumes
that the Impala/hadoop-lzo/Impala-lzo repos are all under the same directory.

Line 289: export KUDU_JAVA_VERSION=1.0.0-SNAPSHOT
> This shouldn't be configurable too?
I'm not quite sure what the right thing to do here is since the Kudu integration is in flux
and we're getting Kudu build artifacts in a different way than other components, so I wanted
to punt for now until that's stabilised.

> It's a bit confusing with 2 concurrent and related reviews. But it seems to
There's not much point making this more configurable right now since we assume these CDH component
tarballs are constructed in a special way our test cluster expects. I'd rather keep it non-configurable
until we've validated that we can drop in different build artifacts just to avoid confusion.

I validated that we can build Impala (but not run tests) with these pointing to nothing-in-particular.
