Subject [jira] [Commented] (HDFS-8481) Erasure coding: remove workarounds in client side stripped blocks recovering
Date Thu, 28 May 2015 22:55:17 GMT

    [ https://issues.apache.org/jira/browse/HDFS-8481?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14563825#comment-14563825
] 

Kai Zheng commented on HDFS-8481:
---------------------------------

Thanks Zhe for the patch. A comment:
A decoder instance was created per decode call in {{decodeAndFillBuffer}}. Please avoid doing
this because it's expensive to prepare for a decoder. By the way, I'm not feeling very good
to have the util because the logic is one of core parts. A util is more like a helper.

contents.
