Subject [jira] [Commented] (HDFS-8728) Erasure coding: revisit and simplify BlockInfoStriped and INodeFile
Date Thu, 16 Jul 2015 21:16:05 GMT

    [ https://issues.apache.org/jira/browse/HDFS-8728?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14630343#comment-14630343
] 

Jing Zhao commented on HDFS-8728:
---------------------------------

If {{EC+repl}} refers to multiple replicas of internal blocks, most of the cases mentioned
above should be fine. HDFS-8619 was filed initially to handle this scenario while HDFS-8543
fixed most of the cases (see [this comment | https://issues.apache.org/jira/browse/HDFS-8619?focusedCommentId=14594201&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14594201]).
But it will be great if we can go through all the cases again and at least add missing tests.
