Aaron T. Myers commented on HDFS-3583:
--------------------------------------
The script looks pretty good to me. One thing I think it missed: JUnit 4 has
support for @BeforeClass and @AfterClass annotations, to indicate that static
methods should be run once before/after a whole test class. JUnit 3 has an
analog that a few of the tests use, which we'll have to take care of. See this
SO question for more info:
