------------------------------
Resolution: Not A Problem
Thanks [~szetszwo] for providing the context information about Mover.
[~archanat], I'm resolving this issue as by design. Let me know if you think it
differently.
> Mover is success even when space exceeds storage quota.

> 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

> Negative value should not be displayed for quota output.
