Subject [jira] [Commented] (HBASE-8410) Basic quota support for namespaces
Date Thu, 09 Jan 2014 22:37:51 GMT

    [ https://issues.apache.org/jira/browse/HBASE-8410?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13867200#comment-13867200
] 

Vandana Ayyalasomayajula commented on HBASE-8410:
-------------------------------------------------

What do  you mean by registered ? In the test case, TestNamespaceAuditor beforeClass method
has the following.
{quote}
		conf.setStrings(CoprocessorHost.MASTER_COPROCESSOR_CONF_KEY,
				NamespaceAuditor.class.getName());
		conf.setStrings(CoprocessorHost.REGION_COPROCESSOR_CONF_KEY,
				NamespaceAuditor.class.getName());
{quote}

Also, the namespace auditor runs at the master and the regions.

> 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.
