Hi [~coheigea], Ok. I will test this case.

> control and configure Hbase data security

> The hbase's performance will be significantly reduced after used Ranger to 
> control and configure Hbase data security. I used following environment to 
> verify issue.
> Test tools:ycsb-0.1.4
> Test environment:
> Node number:4节点
> Node configuration detail is as following:
> Node1、Node2:
> CPU:32 core,Intel(R) Xeon(R) CPU E5-2650 v2 @ 2.60GHz
> memory:128GB
> Node3、Node4
> CPU:48 core,Intel(R) Xeon(R) CPU E5-2670 v3 @ 2.30GHz
> memory:128GB 
> The test result:
> 2. Add one policy and not write audit log, HBase's performance decreased 
> 10.10%;
> 3. Add one policy and write audit log, HBase's performance decreased 12.90%;
> Please refer to result_detail.png.
> This decline is unacceptable in a real environment. It will seriously affect 
> the user to use Ranger.
