------------------------------
bq. I am starting the zk namespace manager in the regionserver so that I don't
have to start one for each region / regionserver. All the regions can use the
same zk namespace manager.
What does it do in the RS? Why is it needed?
Also asked "How often do we do this: getNamespaceTableAndRegionInfo ?"
Thanks.
Basic quota support for namespaces
----------------------------------
Key: HBASE-8410
URL: https://issues.apache.org/jira/browse/HBASE-8410
Project: HBase
Issue Type: Sub-task
Reporter: Francis Liu
Assignee: Vandana Ayyalasomayajula
Attachments: HBASE_8410_1_trunk.patch, HBASE_8410.patch,
HBASE-8410_trunk_2.patch, HBASE-8410_trunk_3.patch, HBASE-8410_trunk_4.patch,
HBASE-8410_trunk_4.patch, HBASE-8410_trunk_5.patch, HBASE-8410_trunk_6.patch,
HBASE-8410_trunk_7.patch, HBASE-8410_trunk_8.patch, HBASE-8410_trunk_9.patch
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.
