Jing Zhao updated HDFS-7484:
----------------------------
Attachment: HDFS-7484.004.patch
Continue the work of Haohui. Based on the 003 patch, add a new method
{{INodesInPath#getExistingINodes}} to return all the existing INodes of a given
INodesInPath instance (i.e., trimming all the null elements), and use this
method to simplify the mkdir logic.
> Simplify the workflow of calculating permission in mkdirs()
