Subject [jira] [Commented] (HDFS-4215) Improvements on INode and image loading
Date Wed, 21 Nov 2012 13:06:00 GMT

    [ https://issues.apache.org/jira/browse/HDFS-4215?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13501942#comment-13501942
] 

Hudson commented on HDFS-4215:
------------------------------

Integrated in Hadoop-Hdfs-trunk #1233 (See [https://builds.apache.org/job/Hadoop-Hdfs-trunk/1233/])
    HDFS-4215. Remove locking from addToParent(..) since it is used in image loading, and
add INode.isFile(). (Revision 1411947)

     Result = SUCCESS

> - There are multiple places checking whether an inode is file by checking !isDirectory()
&& !isSymlink().  Let's add isFile() to INode.
> - When adding child node to parent in image loading, synchronization is not needed.
