He Yongqiang commented on HIVE-3585:
------------------------------------

Although it is so similar to RCFIle, i did not see any reference to RCFile in 
its doc. I assume that will help avoid confusion for its users. But as part of 
Hive, if we got two formats that are so similar to each other, the confusion 
will be thrown to all hive users.
