Description

DefaultContainerExecutor cannot launch container under windows, because bash cannot find the WRAPPER_LAUNCH_SCRIPT.

Path wrapperScriptDst = new Path(containerWorkDir, WRAPPER_LAUNCH_SCRIPT);
String[] command =

{"bash", "-c", wrapperScriptDst.toUri().getPath().toString()}

;
LOG.info("launchContainer: " + Arrays.toString(command));
Suppose that the value of 'wrapperScriptDst' is "C:\hadoop\default_container_executor.sh"
Then wrapperScriptDst.toUri().getPath().toString() will be "/C:/hadoop/default_container_executor.sh", which is a wrong path
