---------------------------------------
Summary: 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

$ hdfs dfsrouteradmin -add /ns1_data ns1 /data

$ hdfs dfsrouteradmin -rm /ns1_data
$ hdfs dfsrouteradmin -add /ns1_data ns1 /data
$ hdfs dfsrouteradmin -ls /ns1_data

$ 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

This is because the quotas of the subclusters still remain after "hdfs
dfsrouteradmin -rm". And "hdfs dfsrouteradmin -add" doesn't reflect the
existing quotas.
