Kai Zheng updated HADOOP-11542:
-------------------------------
    Attachment: HDFS-RAID-GaloisField.java

For helping review, I provided the HDFS-RAID version of GaloisField.java. I 
could provide a diff version instead but looks like it's quite messy. I checked 
it out from branch-2.0.2-alpha branch.
