I realize there may be more comments for documents than for code. So I created a new JIRA HDFS-11033 to track the documentation. ) > 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 > Components: io >Reporter: Kai Zheng >Assignee: SammiChen > Labels: hdfs-ec-3.0-must-do > Fix For: HDFS-7285 > > Attachments: HADOOP-11798-v1.patch, HADOOP-11798-v2.patch, > HADOOP-11798-v3.patch, HADOOP-11798-v4.patch > > > 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.
