Yiqun Lin commented on HDFS-14150:
----------------------------------
Thanks for updating the patch, [~tasanuma0829]! Almost looks great now, only
two nits:
* Can we update the setting's description from single line to multiple lines
like following? It will be look more readable in xml file.
{noformat}
<property>
<name>dfs.federation.router.quota.enable</name>
<value>false</value>
<description>
Set to true to enable quota system in Router. When it's enabled, setting
or clearing sub-cluster's quota directly is not recommended since Router
Admin server will override sub-cluster's quota with global quota.
</description>
</property>
{noformat}
* In test, we need the white space here,
{{long ssQuota = 3*BLOCK_SIZE;}} to {{long ssQuota = 3 * BLOCK_SIZE;}}
> RBF: Quotas of the sub-cluster should be removed when removing the mount point

> 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.
