Vandana Ayyalasomayajula commented on HBASE-8410: ------------------------------------------------- I have added release notes to this jira. Please let me know if I need to modify something. Also should I be creating a backport jira for branch-1 and 98 ? The code base seems quite different and some work needs to be done for the backport. Thanks Ted for committing the patch. > 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 > Fix For: 2.0.0 > > Attachments: 8410-master.9.patch, HBASE-8410-master.1.patch, > HBASE-8410-master.4.patch, HBASE-8410-master.5.patch, > HBASE-8410-master.6.patch, HBASE-8410-master.7.patch, > HBASE-8410-master.9.patch, HBASE-8410-master.patch, HBASE-8410.docx, > HBASE-8410_trunk_14.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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
