Subject [jira] [Commented] (HDFS-5009) NameNode should expose storage information in the LocatedBlock
Date Thu, 29 Aug 2013 11:59:52 GMT

    [ https://issues.apache.org/jira/browse/HDFS-5009?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13753543#comment-13753543

Junping Du commented on HDFS-5009:
----------------------------------

Sure. Nicholas. I am glad to help here.
Yes. That sounds good to me. So StorageTypes[] previously added in HDFS-4985 is duplicated
and keep one here is necessary. Right? BTW, move package for DatanodeStorage is a nice to
have but not must. Isn't it?

> The storage type is optionally reported by the DataNode along with block report. The
NameNode should make this information available to clients via LocatedBlock.
> Also, LocatedBlock is used in reportBadBlocks(..).  We should add storage ID to LocatedBlock.
