Arun Sarin created HDDS-8367:
--------------------------------
Summary: setquota should have a check on usedNamespace
[NameSpacequota]
Key: HDDS-8367
URL: https://issues.apache.org/jira/browse/HDDS-8367
Project: Apache Ozone
Issue Type: Bug
Reporter: Arun Sarin
This is a negative scenario that was tested
While modifying setquota NameSpacequota we should have a check on usedNamespace
already consumed by the volume.
For Example these are the two possible scenarios:
# In a case when namespace quota is not defined on the volume and there are
some n numbers of buckets already created in that volume. Then if we are trying
to setquota on that volume, there should be a check that it should not allow us
to set a namespacequota less than usedNamespace
# Second similiar scenario is Create volume with namespace quota --> create
buckets --> Clear namespace quota --> Assign namespace quota less than already
created buckets
PFB the steps to recreate Scenario 1 :
Step 1 - Create volume without namespace quota
{noformat}
[root@quasar-tvqwpy-1 ~]# ozone sh volume create volume3
23/04/04 04:49:13 INFO rpc.RpcClient: Creating Volume: volume3, with hdfs as
owner and space quota set to -1 bytes, counts quota set to -1{noformat}
Step 2 - Check volume info
{noformat}
[root@quasar-tvqwpy-1 ~]# ozone sh volume info /volume3
{
"metadata" : { },
"name" : "volume3",
"admin" : "hdfs",
"owner" : "hdfs",
"quotaInBytes" : -1,
"quotaInNamespace" : -1,
"usedNamespace" : 0,
"creationTime" : "2023-04-04T04:49:13.520Z",
"modificationTime" : "2023-04-04T04:49:13.520Z",
"acls" : [ {
"type" : "USER",
"name" : "hdfs",
"aclScope" : "ACCESS",
"aclList" : [ "ALL" ]
}, {
"type" : "GROUP",
"name" : "hdfs",
"aclScope" : "ACCESS",
"aclList" : [ "ALL" ]
}, {
"type" : "GROUP",
"name" : "hadoop",
"aclScope" : "ACCESS",
"aclList" : [ "ALL" ]
} ],
"refCount" : 0
}{noformat}
Step 3 - Create buckets
{noformat}
[root@quasar-tvqwpy-1 ~]# ozone sh bucket create /volume3/bucket1
23/04/04 04:49:44 INFO rpc.RpcClient: Creating Bucket: volume3/bucket1, with
server-side default bucket layout, hdfs as owner, Versioning false, Storage
Type set to DISK and Encryption set to false
[root@quasar-tvqwpy-1 ~]# ozone sh bucket create /volume3/bucket2
23/04/04 04:49:50 INFO rpc.RpcClient: Creating Bucket: volume3/bucket2, with
server-side default bucket layout, hdfs as owner, Versioning false, Storage
Type set to DISK and Encryption set to false
[root@quasar-tvqwpy-1 ~]# ozone sh bucket create /volume3/bucket3
23/04/04 04:49:56 INFO rpc.RpcClient: Creating Bucket: volume3/bucket3, with
server-side default bucket layout, hdfs as owner, Versioning false, Storage
Type set to DISK and Encryption set to false
[root@quasar-tvqwpy-1 ~]# ozone fs -ls ofs://ozone1/volume3
Found 3 items
drwxrwxrwx - hdfs hdfs 0 2023-04-04 04:49

ofs://ozone1/volume3/bucket2
drwxrwxrwx - hdfs hdfs 0 2023-04-04 04:49

Step 4 - setquota [This must have failed]
{noformat}
[root@quasar-tvqwpy-1 ~]# ozone sh volume setquota --namespace-quota 1
/volume3{noformat}
Step 5 - Verify
{noformat}
[root@quasar-tvqwpy-1 ~]# ozone sh volume info /volume3

"metadata" : { },
"name" : "volume3",
"admin" : "hdfs",
"owner" : "hdfs",

"quotaInNamespace" : 1,
"usedNamespace" : 3,
"creationTime" : "2023-04-04T04:49:13.520Z",
