Doug Cutting commented on HADOOP-1792:
--------------------------------------
Is anyone else seeing this? There were changes to DF.java in 0.14, but none
that should cause this. Are you still running under a Cygwin shell? We depend
on Cygwin binaries being on $PATH, including at least 'df' and 'bash'.
