Laurent Tardif commented on FLINK-1848:
---------------------------------------
There also a little issue in the test that validate FileOutputFormat class.
ex : in the method testCreateNonParallelLocalFS
tmpOutFile = new File(tmpOutPath.getAbsolutePath()+"/1");
isntead of :
tmpOutFile = new File(tmpOutPath.getAbsolutePath()+File.separatorChar+"1");
For the bug : the issue happen (for me) in the mkdirs function of the
localFileSystem class when it didnot detect than file:/C/ is the root of the
filesystem.
also, it look strange not to verify at the begining of the function, that the
parameter is a directory, and that we do not need to recurse up to the root of
the filesystem to validate the path
public boolean mkdirs(final Path f) throws IOException {
if (pathToFile(f).isDirectory()) {return true ;}
