> TestJobTrackerQuiescence is a test case introduced in https://issues.apache.org/jira/browse/MAPREDUCE-4328. 
> Here is the code generating a file path on DFS:
> {code}
>  final Path testDir = 
>     new Path(System.getProperty("test.build.data", "/tmp"), "jt-safemode");
> {code}
> This doesn't work on Windows because "test.build.data" would have a driver name with ":" (e.g. D:/hadoop/build/test). However, this is not a valid path name on DFS because colon is disallowed (See DFSUtil#isValidName()).
> A similar problem happens to TestFileLengthOnClusterRestart#testFileLengthWithHSyncAndClusterRestartWithOutDNsRegister()
> {code}
>   Path path = new Path(MiniDFSCluster.getBaseDir().getPath(), "test");
> {code}
