Hairong Kuang updated HADOOP-3187:
----------------------------------
Attachment: quota4.patch
1, FSDirectory.updateCount() is changed to be updateCountForInodeWithQuota.
2. I still keep quota & count to be long. So in the future when dfs grows, we
do not need to make any change.
The patch Incorporated rest of Konstantin's comments.
