Jonathan Barber updated HADOOP-9493:
------------------------------------
Attachment: HADOOP-9493.patch
Patch is the same as previous version but with an additional import of the
constant MAXFD.
MAXFD is used in the method _Popen3Env._run_child(), but this method doesn't
appear to be called from anywhere.
