Subject [jira] [Commented] (HDFS-8319) Erasure Coding: support decoding for stateful read
Date Fri, 05 Jun 2015 01:15:38 GMT

    [ https://issues.apache.org/jira/browse/HDFS-8319?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14573902#comment-14573902
] 

Zhe Zhang commented on HDFS-8319:
---------------------------------

I see, basically with the current algorithm, the {{if (alignedStripe.fetchedChunksNum == dataBlkNum)}}
logic is never reached. We can address that when we add "hedged" recovery reads.

+1 on the 05 patch. Thanks Jing for the great work!
