I have already pushed below one. :)

> We have seen some tests had been used the path {{test/build/data}} to store files, so
leaking files which fail the new post-build RAT test checks on Jenkins (and dirtying all development
systems with paths which {{mvn clean}} will miss.
> In order not to occur these bugs such as MAPREDUCE-6589 and HDFS-9571 again, we'd like
to introduce new utility methods to get a temporary directory path easily, and use the methods
in tests.
