Archana T created HDFS-8465:
-------------------------------

             Summary: Mover is success even when space exceeds storage quota.
                 Key: HDFS-8465
                 URL: https://issues.apache.org/jira/browse/HDFS-8465
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: balancer & mover
            Reporter: Archana T
            Assignee: surendra singh lilhore



*Steps :*
1. Create directory /dir 
2. Set its storage policy to HOT --
hdfs storagepolicies -setStoragePolicy -path /dir -policy HOT

3. Insert files of total size 10,000B  into /dir.
4. Set above path "/dir" ARCHIVE type quota to 5,000B --
hdfs dfsadmin -setSpaceQuota 5000 -storageType ARCHIVE /dir
{code}
hdfs dfs -count -v -q -h -t  /dir
   DISK_QUOTA    REM_DISK_QUOTA     SSD_QUOTA     REM_SSD_QUOTA ARCHIVE_QUOTA REM_ARCHIVE_QUOTA
PATHNAME
         none               inf          none               inf         4.9 K            
4.9 K /dir
{code}
5. Now change policy of '/dir' to COLD
6. Execute Mover command

*Observations:*
1. Mover is successful moving all 10,000B to ARCHIVE datapath.

2. Count command displays negative value '-59.4K'--
{code}
hdfs dfs -count -v -q -h -t  /dir
   DISK_QUOTA    REM_DISK_QUOTA     SSD_QUOTA     REM_SSD_QUOTA ARCHIVE_QUOTA REM_ARCHIVE_QUOTA
PATHNAME
         none               inf          none               inf         4.9 K           -59.4
K /dir
{code}
*Expected:*
Mover should not be successful as ARCHIVE quota is only 5,000B.
Negative value should not be displayed for quota output.
