Description

From HDFS-14143

$ 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

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