> The symptom is if PigProcessor fail, MRInput is not closed. On Windows, this creates a problem since Pig client cannot remove the input file.
> In general, if a task fail, Tez shall close all input/output handles in cleanup. MROutput is closed in MROutput.abort() which Pig invokes explicitly right now. Attach a demo patch.
