Takanobu Asanuma commented on HDFS-14143:
-----------------------------------------
Actually, the problem I saw is different. Seems {{clrQuota}} works well. Sorry
for the confusion.
I didn't use {{clrQuota}}. I just removed and added the mount point.
{noformat}
$ hdfs dfsrouteradmin -add /ns1_data ns1 /data
$ hdfs dfsrouteradmin -setQuota /ns1_data -nsQuota 10 -ssQuota 10
$ hdfs dfsrouteradmin -ls /ns1_data
Source Destinations Owner
Group Mode Quota/Usage
/ns1_data ns1->/data tasanuma
users rwxr-xr-x [NsQuota: 10/1, SsQuota:
10 B/0 B]
$ hdfs dfsrouteradmin -rm /ns1_data
$ hdfs dfsrouteradmin -add /ns1_data ns1 /data
$ hdfs dfsrouteradmin -ls /ns1_data
Source Destinations Owner
Group Mode Quota/Usage
/ns1_data ns1->/data tasanuma
users rwxr-xr-x [NsQuota: -/-, SsQuota:
-/-]
$ hadoop fs -put file1 /ns1_data/file1
put: The DiskSpace quota of /data is exceeded: quota = 10 B = 10 B but
diskspace consumed = 402653184 B = 384 MB
{noformat}
This is because the quotas of the subclusters still remain after "{{hdfs
dfsrouteradmin -rm}}". And "{{hdfs dfsrouteradmin -add}}" doesn't reflect the
existing quotas.
