Subject [jira] [Commented] (HDFS-3363) blockmanagement should stop using INodeFile & INodeFileUC
Date Thu, 03 May 2012 17:54:51 GMT

    [ https://issues.apache.org/jira/browse/HDFS-3363?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13267632#comment-13267632

Tsz Wo (Nicholas), SZE commented on HDFS-3363:

Block management should only care about blocks but not the namespace.  It should not know
anything about the namespace.  It makes sense to define a BlockCollection interface for INodeFile
and INodeFileUnderConstruction.  We probably need two interfaces, one for mutable collections
and another one for immutable collections.

> Blockmanagement should stop using INodeFile and INodeFileUnderConstruction. One way would
be to create an interface, like BlockColletion, that is passed along to the blockmanagement.
