Jakob Homan commented on HDFS-781:
----------------------------------

Patch looks good except that, if we're (correctly) improving the test directory 
name, we should also fix its writing directly to /tmp rather than using the 
build property ({code}System.getProperty("test.build.data","/tmp"){code}) 
(HADOOP-5916).
