In summary, as solution they recommend to create the parent folders, there is also a patch that is supposed to be fixed at 2.0.3 [1]
Tom White added a comment - 30/Nov/12 21:36 This fixes the problem by creating parent directories if they don't already exist. Without the fix the test would fail about 4 times in 10; with the fix I didn't see a failure.
It looks like the most similar issue that I could find in the hadoop bugs database
