Subject [jira] [Commented] (HDFS-3363) blockmanagement should stop using INodeFile & INodeFileUC
Date Tue, 08 May 2012 14:03:54 GMT

    [ https://issues.apache.org/jira/browse/HDFS-3363?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13270469#comment-13270469
] 

Hudson commented on HDFS-3363:
------------------------------

Integrated in Hadoop-Mapreduce-trunk #1073 (See [https://builds.apache.org/job/Hadoop-Mapreduce-trunk/1073/])
    HDFS-3363. Define BlockCollection and MutableBlockCollection interfaces so that INodeFile
and INodeFileUnderConstruction do not have to be used in block management.  Contributed by
John George (Revision 1335304)

     Result = SUCCESS
