----------------------------------
Summary: Refactor raw erasure coders
Key: HADOOP-13010
URL: https://issues.apache.org/jira/browse/HADOOP-13010
Project: Hadoop Common
Issue Type: Sub-task
Reporter: Kai Zheng
Assignee: Kai Zheng
Fix For: 3.0.0
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.
