space quota issue: deleting snapshot doesn't update the usage of table

Steps: 1:

set_quota TYPE => SPACE, TABLE => 'bugatti', LIMIT => '7M', POLICY => NO_WRITES_COMPACTIONS

2: ./hbase pe --table="bugatti" --nomapred --rows=200 sequentialWrite 10

3: ./hbase pe --table="bugatti" --nomapred --rows=200 sequentialWrite 10

4: snapshot 'bugatti','bugatti_snapshot'

5: ./hbase pe --table="bugatti" --nomapred --rows=200 sequentialWrite 10

6: major_compact 'bugatti'

7: delete_snapshot 'bugatti_snapshot'

now check the usage and observe that it is not getting updated.
