Kai Zheng commented on HADOOP-11740:
------------------------------------

Thanks for the update. I looked the new patch, just two minor comments:
1. In the test codes, may be better to use {{ErasureCoder}} instead of 
{{AbstractErasureEncoder}} or {{AbstractErasureDecoder}} since the interface 
type is good enough, which is why we're here. With this refining, from caller's 
point of view, nothing different from between encoder and decoder, so it should 
use the common interface.
2. Those unnecessary Javadoc are there to conform Javadoc conventions and 
format. In future someone may fill them. I suggest we don't remove them, you 
can find so many in the project.
