Augusto Souza commented on MAPREDUCE-5269:
------------------------------------------
Does anyone know why the TestReduceTask is failing because of the definition of
the IFile.Writer constructor even knowing I have changed the signature of this
contructor in the patch I submitted?
It is like jenkins is running this test with an older version of the IFile
class than the one my patch propose.
Also, TestJobConf in my development machine is also breaking on trunk, do I
have to look at this?
Thanks in advance for any help.
