Ashish Singhi commented on HBASE-8410:
--------------------------------------

In the release note example we need to correct the command used, there is no shell command {{namespace_create}} instead it should be {{create_namespace}}.
Also if possible can we also mention in the example how a user can unset the maxtable/maxregions in the namespace
{code}alter_namespace 'ns3', {METHOD => 'unset', 'hbase.namespace.quota.maxtables'} {code}

> This task involves creating an observer which provides basic quota support to namespaces in terms of (1) number of tables and (2) number of regions. The quota support can be enabled by setting:
> <property>
>     <name>hbase.coprocessor.region.classes</name>
>     <value>org.apache.hadoop.hbase.namespace.NamespaceController</value>
> </property>
> <property>
>     <name>hbase.coprocessor.master.classes</name>
>     <value>org.apache.hadoop.hbase.namespace.NamespaceController</value>
> </property>
> in the hbase-site.xml.
> To add quotas to namespace, while creating namespace properties need to be added.
> Examples:
> 1. namespace_create 'ns1', {'hbase.namespace.quota.maxregion'=>'10'}
> 2. 1. namespace_create 'ns2', {'hbase.namespace.quota.maxtables'=>'2'}, {'hbase.namespace.quota.maxregion'=>'5'}
> The quotas can be modified/added to namespace at any point of time.
