Subject [jira] [Updated] (HDFS-8120) Erasure coding: created util class to analyze striped block groups
Date Tue, 14 Apr 2015 19:47:00 GMT

     [ https://issues.apache.org/jira/browse/HDFS-8120?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Zhe Zhang updated HDFS-8120:
----------------------------
    Attachment: HDFS-8120.004.patch

The patch adds tests to {{BlockManager#checkReplicaCorrupt}}. [~jingzhao] Could you take a
look and see if them are OK?

I removed the changes to {{DFSStripedOutputStream#writeParityCellsForLastStripe}}. I think
we need a follow-on JIRA on that logic as well as {{locateFollowingBlock}}.
