https://github.com/apache/spark/pull/6653
[minor] [build] Use custom temp directory during build.
Even with all the efforts to cleanup the temp directories created by
unit tests, Spark leaves a lot of garbage in /tmp after a test run.
This change overrides java.io.tmpdir to place those files under the
build directory instead.
After an sbt full unit test run, I was left with > 400 MB of temp
files. Since they're now under the build dir, it's much easier to
clean them up.
Also make a slight change to a unit test to make it not pollute the
source directory with test data.
