Subject [jira] [Commented] (HADOOP-13019) Implement ErasureCodec for HitchHiker XOR coding
Date Sat, 18 Jun 2016 00:34:05 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-13019?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15337333#comment-15337333

Zhe Zhang commented on HADOOP-13019:
------------------------------------

Thanks [~lewuathe]. I think enabling HH is a very useful task for 3.0-alpha1 release.

Patch itself looks good. [~drankye] I have a more general question about the {{AbstractErasureCodec}}
structure. If all classes extending the abstract class only contain trivial code, should we
consider moving this layer of abstraction?
