Tsz Wo (Nicholas), SZE updated HDFS-4209:
-----------------------------------------
Description:
In the addNode/addChild/addChildNoQuotaCheck methods, returning the same INode
back is not useful. It is better to simply return a boolean to indicate
whether the inode is added.
Also, the value of childDiskspace parameter is always UNKNOWN_DISK_SPACE. In
most cases, the value of the pos parameter is length - 1.
was:
- FSDirectory.addToParent(..) is only used by image loading so that
synchronization, modification time update and space count update are not needed.
- There are multiple places checking whether an inode is file by checking
!isDirectory() && !isSymlink(). Let's add isFile() to INode.
- In the addNode/addChild/addChildNoQuotaCheck methods, returning the same
INode back is not useful. It is better to simply return a boolean to indicate
whether the inode is added. Also, the value of childDiskspace parameter is
always UNKNOWN_DISK_SPACE.
Summary: Clean up the addNode/addChild/addChildNoQuotaCheck methods in
FSDirectory (was: Clean up FSDirectory and INode)
