Tsz Wo (Nicholas), SZE updated HDFS-4243:
-----------------------------------------
Description:
The method replaces an existing child with a new child. However, it does not
take care the case the child also an INodeDirectory. In such case, the parent
pointers of the children of the child have to be updated to the new child.
Only FSDirectory.unprotectedSetQuota(..) call this method so that the child is
always an INodeDirectory.
