>  HADOOP-2656  changes the way BlockScanner and BlockScannerThread are created. TestHDFSServerPorts
tries to create a DataNode object, but expects a failure while starting it. As part of creating
DataNode object we create BlockScanner object but not its corresponding BlockScannerThread
as Daemon. While in shutdown() we check if BlockScannerThread is not null, then call BlockScanner.shutdown()
to close a reference to LogFile it holds.
> Now, on NFS mount and Windows, if a reference to file remains deleting the directory
either leaves a .nfsXXXXX file or is not allowed (on windows). This was causing the test to
fail.
