> 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.
