Wei-Chiu Chuang commented on HADOOP-11798: ------------------------------------------ BTW I only looked at the Java code. Someone ([~drankye]?) should take a look at the native implementation. Thanks. > 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. It can also be > used in HitchHiker coder. Therefore a native implementation of it would be > deserved for performance gain. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-issues-h...@hadoop.apache.org
