Philip Zeyliger commented on HADOOP-5948:
-----------------------------------------

+1 on making tests faster.

   private static String TEST_ROOT_DIR =
    new File(System.getProperty("test.build.data", "/tmp")).toURI()
    .toString().replace(' ', '+');
{quote}

Definitely off-topic, but I've seen this line, in many different incantations, throughout the code base.  Is this something that could be added to UtilsForTest.java once and for all?  Do you know why the string replacement is necessary?

> TestJavaSerialization currently uses MiniMR/DFS cluster. This test can be done with local job runner also. This reduces the run time of the test from 61 seconds to 6 seconds.
