> TestJsonStorageLoader fails due to small differences in the way HashMaps are
> printed out. The HashMap specification
> (http://docs.oracle.com/javase/1.5.0/docs/api/java/util/HashMap.html)
> mentions that "This class makes no guarantees as to the order of the map; in
> particular, it does not guarantee that the order will remain constant over
> time.", so PIG testcases should not rely on the order in which the HashMap
> items are printed out.
> testJsonLoaderStorage1 explicitly does this comparison:
> Testcase: testJsonLoaderStorage1 took 2.25 sec
> FAILED
