Subject [jira] [Commented] (HDFS-7837) Erasure Coding: allocate and persist striped blocks in NameNode
Date Mon, 09 Mar 2015 18:00:49 GMT

    [ https://issues.apache.org/jira/browse/HDFS-7837?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14353289#comment-14353289

Zhe Zhang commented on HDFS-7837:

HDFS-7411 has renamed and refactored {{isReplicationInProgress}} into {{processBlocksForDecomInternal}}
and {{isSufficientlyReplicated}}. 

[~jingzhao] Do you mind rebasing this patch? [~andrew.wang] brought up a suggestion that we
should probably push some of this JIRA to trunk; looks like several JIRAs are lined up to
change the block management layer.
