Title: Fix committing problem when saving as text file on hdfs 

Tested on hadoop 2.0.3-alpha.

When saving RDD as text file on hdfs, file output will be cleaned after committing. It is needed to call commitJob after commitTask to fix this problem.

Also updated building file to hadoop 2.0.3-alpha.
