Hudson commented on HDFS-4215:
------------------------------
Integrated in Hadoop-Yarn-trunk #43 (See
[https://builds.apache.org/job/Hadoop-Yarn-trunk/43/])
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.
