Subject [jira] [Created] (HADOOP-11798) Native raw erasure coder in XOR codes
Date Fri, 03 Apr 2015 10:35:53 GMT
Kai Zheng created HADOOP-11798:
----------------------------------

             Summary: Native raw erasure coder in XOR codes
                 Key: HADOOP-11798
                 URL: https://issues.apache.org/jira/browse/HADOOP-11798
             Project: Hadoop Common
          Issue Type: Sub-task
            Reporter: Kai Zheng
            Assignee: Kai Zheng


Raw XOR coder is utilized in Reed-Solomon erasure coder in an optimization to recover only
one erased block which is in most often case. It can also be used in HitchHiker coder. Therefore
a native implementation of it would be deserved for performance gain.
