+When a work load increases on a cluster due to multiple users or user
requests, the system needs to prioritize the users or the user requests for a
smooth operation.
+This is handled by the HBase quota feature. The quota allows the admin to
limit the number of tables, regions, or request in a system.
+By default the quota function is disabled. To enable the quota, change the
value of parameter `hbase.quota.enabled` to `true` in _hbase-site.xml_ file for
all HMaster and HRegionServer machines.
+By default quota setting cache refresh time period
`'hbase.quota.refresh.period'` is set to 5*60000(5 mins). Which means a user
has to wait for maximum of 5 mins to get his quota settings updated.
+Request Number Quota reserves the number of requests that is allowed to
execute on a particular table or namespace in any given time by a user or users
with similar name.
+Request size quota reserves the size of the requests that is allowed to
execute on a particular table or a namespace in any given time by a user or
users with similar name.
+The valid size units are B(byte), K(kilobyte), M(megabyte), G(gigabyte),
T(terabyte), and P(petabyte).
