Creating a table stored a sequence file and trying to write data into it using Pig or MR fails with NPE.
Unit tests added and they pass.

-- Moved the setting of mapred output key and value class to FileOutputFormat, so that the updated props are available only before the record writer is created. 
-- Added a test case for text MR job.
