> 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.
