-------------------------------
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.
