Date Wed, 01 Apr 2015 13:30:53 GMT

     [ https://issues.apache.org/jira/browse/HDFS-8013?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Kai Zheng updated HDFS-8013:
----------------------------
    Description: Similar to HDFS-7369, for *non-stripping* erasure coding, NameNode may detect
some erasure coding blocks are erased, so will schedule and distribute recovery work to DataNode
to reconstruct such blocks.   (was: Similar to HDFS-7369, for non-stripping erasure coding,
NameNode may detect some erasure coding blocks are erased, so will schedule and distribute
recovery work to DataNode to reconstruct such blocks. )
