stack commented on HBASE-4120:
------------------------------
Thank you for pointing out this interesting contribution. Over on github I see
a tar.gz and a big patch. I could try and parse the patch to figure what it
adds -- I see lots of jsp and a bunch of new classes in a new allocation
package that look intriguing. Any chance of a more in-depth description of
what this contribution does? (How this high and low level grouping works, what
is done to hbase to ensure priorities are respected, etc.)
Thank you.

> Key: HBASE-4120
> URL: https://issues.apache.org/jira/browse/HBASE-4120
> Project: HBase
> Issue Type: New Feature
> Components: master, regionserver
> Affects Versions: 0.90.2
> Reporter: Liu Jia
>
> The HBase isolation and allocation tool is designed to help users manage
> cluster resource among different application and tables.
> When we have a large scale of HBase cluster with many applications running on
> it, there will be lots of problems. In Taobao there is a cluster for many
> departments to test their applications performance, these applications are
> based on HBase. With one cluster which has 12 servers, there will be only one
> application running exclusively on this server, and many other applications
> must wait until the previous test finished.
> After we add allocation manage function to the cluster, applications can
> share the cluster and run concurrently. Also if the Test Engineer wants to
> make sure there is no interference, he/she can move out other tables from
> this group.
> In groups we use table priority to allocate resource, when system is busy; we
> can make sure high-priority tables are not affected lower-priority tables
> Different groups can have different region server configurations, some groups
> optimized for reading can have large block cache size, and others optimized
> for writing can have large memstore size.
> Tables and region servers can be moved easily between groups; after changing
> the configuration, a group can be restarted alone instead of restarting the
> whole cluster.

> We hope our work is helpful.
