Subject [jira] [Commented] (HDFS-11033) Add documents for native raw erasure coder in XOR codes
Date Wed, 19 Oct 2016 17:47:58 GMT

    [ https://issues.apache.org/jira/browse/HDFS-11033?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15589370#comment-15589370

Wei-Chiu Chuang commented on HDFS-11033:

Looks mostly good to me. 

bq. For default RS codec, there is also a native implementation which leverages Intel ISA-L
library to improve the encoding and decoding calculation.
You may want to be more specific by saying "to improve the performance of codec."
