Subject [jira] [Commented] (HDFS-7353) Raw Erasure Coder API for concrete encoding and decoding
Date Tue, 20 Jan 2015 00:47:34 GMT

    [ https://issues.apache.org/jira/browse/HDFS-7353?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14283238#comment-14283238

Kai Zheng commented on HDFS-7353:
---------------------------------

I agree the naming might not be very clear or concrete but I guess the abstraction has some
benefits so that it's flexible and has potential to contain more APIs some of which I'm going
to add.

> This is to abstract and define raw erasure coder API across different codes algorithms
like RS, XOR and etc. Such API can be implemented by utilizing various library support, such
as Intel ISA library and Jerasure library.
