Attaching patch with
1. Added testcases for submission errors, single mapper/reducer in chain, one
of the maps throwing an exception thus breaking the chain, one of the maps
eats up all the input and doesn't output any.
2. Made helper class org.apache.hadoop.mapreduce.lib.Chain a public class. And
changed old api code to reuse the code from new api.
3. Fixed some indentation issues
