> This is a large patch, please let me know if I should split it up and/or use the code reviewer tool. I tested it on linux and verified that it did not cause any unit test regressions.
> This patch fixes many unix-specific assumptions in code and tests:
> # Using "/" as a path separator. On windows, the right separator is "\". Fix: create a new Path object with the directory and subdirectory names, which handles using the right separator.
> # Determining whether a path is absolute by testing if it begins with "/". Fix: Create a new File object and use isAbsolute().
> # Generating a pathname by concatenating "file://", getTestCaseDir(), File.separator, and the file name. This is wrong because this is a URI, and File.separator is "/" on unix but "\" on windows. Fix: New helper method getTestCaseFileUri solves this.
> # Create directories by using "mkdir" shell command with hard-coded file separators. Fix: Create a new File object and use mkdirs().
> # Scripts that use unix-only commands (ls, echo, etc.). Fix: Implement windows-specific commands and use Shell.WINDOWS to pick the right one at runtime.
> # Assume that perl exists in TestShellActionExecutor.testPerlScript. It doesn't on Windows. Fix: skip the test on Windows.
> # Use the test case name as part of the temp directory name in order to ensure directories are unique. This can cause issues on Windows. Fix: Use a random UUID instead.
> # As a result of using getTestCaseUri, some test case verification that uses string equality fails. (TestLiteWorkflowAppService) Fix: use URI equivalence instead of string equality.
> # AdminServlet tests verify that system variables are working by checking for a USER variable. This is called USERNAME in windows. Fix: On Windows, check for USERNAME instead.
> # TestHostnameFilter checks that "localhost" is in the filter. On Windows, this is "127.0.0.1". Fix: On Windows, check for 127.0.0.1 instead.
> On windows there are still several tests failing. I hope to spend some time fixing these later:

> Failed tests:
> testActionCheck(org.apache.oozie.command.wf.TestActionCheckXCommand)
> testActionCheckTransientDuringLauncher(org.apache.oozie.command.wf.TestActionCheckXCommand)
> testActionCheckTransientDuringMRAction(org.apache.oozie.command.wf.TestActionCheckXCommand)
> testCoordinatorActionCommands(org.apache.oozie.sla.TestSLAEventGeneration): expected:<NOT_STARTED> but was:<IN_PROCESS>
> testChmodWithGlob(org.apache.oozie.action.hadoop.TestFsActionExecutor): expected:<rw[-]------> but was:<rw[x]------>
> Tests in error:
> testWaitFor(org.apache.oozie.test.TestXTestCase): could not delete path [D:\apache\oozie\core\target\test-data\oozietests\org.apache.oozie.test.TestXTestCase$MyXTestCase\testWaitFor\conf\oozie-site.xml]
> testBaseDir(org.apache.oozie.test.TestXTestCase): could not delete path [D:\apache\oozie\core\target\test-data\oozietests\org.apache.oozie.test.TestXTestCase$MyXTestCase\testBaseDir\conf\oozie-site.xml]

> How to run unit tests in windows:
> # You will need to build hadoop-core from branch-1-win and install it into your local maven cache. 
> # In the root pom.xml, replace the dummy value in HADOOP_HOME with the path to the hadoop directory. The minicluster tests require bin\winutils.exe to be in this directory.
> # In the root pom.xml (and hadooplibs version 1 pom.xmls, if OOZIE-1490 is not committed yet) change the hadoop version to the version built from branch-1-win.
> # May also need to use Hive 0.11 with the windows fixes.
