Kai Zheng commented on HADOOP-11646:
------------------------------------
I uploaded a new patch. In addition to above changes, I also reverted back the
{{coder}} package from {{blockcoder}}. When I have finally almost all the codes
in hand, the original package looks more comfortable to me. In
{{org.apache.hadoop.io.erasurecode}} we will have {{coder}}, {{codec}}, and
{{rawcoder}} sub-packages.
