--------------------------------------
Summary: [HDFS-Quota]Quota is getting updated after storage policy
is modified even before mover command is executed.
Key: HDFS-8467
URL: https://issues.apache.org/jira/browse/HDFS-8467
Project: Hadoop HDFS
Issue Type: Bug
Reporter: Jagadesh Kiran N
Assignee: surendra singh lilhore
a. create a directory
{code}
./hdfs dfs -mkdir /d1
{code}
b. Set storage policy HOT on /d1
{code}
./hdfs storagepolicies -setStoragePolicy -path /d1 -policy HOT
{code}
c. Set space quota to disk on /d1
{code}
./hdfs dfsadmin -setSpaceQuota 10000 -storageType DISK /d1
{code}
{code}
./hdfs dfs -count -v -q -h -t /d1
DISK_QUOTA REM_DISK_QUOTA SSD_QUOTA REM_SSD_QUOTA ARCHIVE_QUOTA
REM_ARCHIVE_QUOTA PATHNAME
9.8 K 9.8 K none inf none
inf /d1
{code}
d. Insert 2 file each of 1000B
{code}
./hdfs dfs -count -v -q -h -t /d1
DISK_QUOTA REM_DISK_QUOTA SSD_QUOTA REM_SSD_QUOTA ARCHIVE_QUOTA
REM_ARCHIVE_QUOTA PATHNAME
9.8 K 3.9 K none inf none
inf /d1
{code}
e. Set ARCHIVE quota on /d1
{code}
./hdfs dfsadmin -setSpaceQuota 10000 -storageType ARCHIVE /d1
./hdfs dfs -count -v -q -h -t /d1
DISK_QUOTA REM_DISK_QUOTA SSD_QUOTA REM_SSD_QUOTA ARCHIVE_QUOTA
REM_ARCHIVE_QUOTA PATHNAME
9.8 K 3.9 K none inf 9.8 K
9.8 K /d1
{code}
f. Change storagepilicy to COLD
{code}
./hdfs storagepolicies -setStoragePolicy -path /d1 -policy COLD
{code}
g. Check REM_ARCHIVE_QUOTA Value
{code}
./hdfs dfs -count -v -q -h -t /d1
DISK_QUOTA REM_DISK_QUOTA SSD_QUOTA REM_SSD_QUOTA ARCHIVE_QUOTA
REM_ARCHIVE_QUOTA PATHNAME
9.8 K 9.8 K none inf 9.8 K
3.9 K /d1
{code}
Here even when 'Mover' command is not run, quota of REM_ARCHIVE_QUOTA is
reduced and REM_DISK_QUOTA is increased.
Expected : After Mover is success quota values has to be changed.
