Ming Ma updated HDFS-9360:
--------------------------
Description: For a directory that doesn't have any storage policy defined,
its storage quota usage is deducted when a file is deleted (addBlock skips
storage quota usage update in such case). This means negative value for storage
quota usage. Later after applications set the storage policy and storage type
quota, it allows the applications to use more than its storage type quota.
(was: For a directory that doesn't have any storage policy defined, its quota
usage is deducted when a file is deleted. This means incorrect value for
storage quota usage. Later when applications set the storage type, it can
exceed its storage quota.)
> Storage type usage isn't updated properly after file deletion
