> 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.
> git entry : https://github.com/ICT-Ope/HBase_allocation .
> We hope our work is helpful.
