hdfsSetWorkingDirectory()
Supported by libMapRClient for hadoop-2.x
Set the working directory. All relative paths will be resolved relative to it.
For example, if you call this API to set the
working directory to /mycluster/myvolume and
subsequently call hdfsOpenFile() with the path
/temp/tmp.txt, the full path to the file to open is
assumed to be /mycluster/myvolume/temp/tmp.txt.
