Ming Ma updated HDFS-9360:
--------------------------
Attachment: HDFS-9360.patch
The issue is in {{computeQuotaUsage}}, where {{bsps.getPolicy}} returns the
default storage policy instead of null pointer. Here is the patch with the unit
test that verifies the fix. [~xyao] or others, can you please take a look?
> Storage type usage isn't updated properly after file deletion

> 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.
