>
> 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.
