Kai Zheng updated HADOOP-13010:
-------------------------------
Attachment: HADOOP-13010-v7.patch
Updated the patch fixing the failure mentioned above. Also manually checked
many related tests. Not sure why the Jenkins not worked for this as before but
guess the latest change came across both HADOOP and HDFS sides.

> This will refactor raw erasure coders according to some comments received so
> far.
> * As discussed in HADOOP-11540 and suggested by [~cmccabe], better not to
> rely class inheritance to reuse the codes, instead they can be moved to some
> utility.
> * Suggested by [~jingzhao] somewhere quite some time ago, better to have a
> state holder to keep some checking results for later reuse during an
> encode/decode call.
> This would not get rid of some inheritance levels as doing so isn't clear yet
> for the moment and also incurs big impact. I do wish the end result by this
> refactoring will make all the levels more clear and easier to follow.
