Takanobu Asanuma commented on HDFS-14150: ----------------------------------------- {quote}This won't be easy to do since sub-clusters maybe have different existing quota values. {quote} Is it about {{Multiple subclusters}}? I'm still wondering if it is possible that both of sub-clusters and Router(StateStore) can synchronize with each other. I mean, updating not only the quota usage but also the quota definition periodically would be good. The current specification is following and a little confusing. * If users use setQuota/crlQuota in Router admin, the quota definition will be sync to the subclusters. * Even if users use setQuota/crlQuota in subclusters, the quota definition isn't sync to the Router(StateStore). > RBF: Quotas of the sub-cluster should be removed when removing the mount point > ------------------------------------------------------------------------------ > > Key: HDFS-14150 > URL: https://issues.apache.org/jira/browse/HDFS-14150 > Project: Hadoop HDFS > Issue Type: Improvement > Reporter: Takanobu Asanuma > Assignee: Takanobu Asanuma > Priority: Major > Labels: RBF > > From HDFS-14143 > {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".
