Colm O hEigeartaigh commented on RANGER-1729: --------------------------------------------- I wonder how much the slowdown could have been caused by policy retrieval - if you change the default value for policy retrieval from 30 seconds to say 10000 seconds, what would be the slowdown? > The hbase's performance will be significantly reduced after used Ranger to > control and configure Hbase data security > -------------------------------------------------------------------------------------------------------------------- > > Key: RANGER-1729 > URL: https://issues.apache.org/jira/browse/RANGER-1729 > Project: Ranger > Issue Type: Bug > Components: Ranger > Reporter: Qiang Zhang > Assignee: Qiang Zhang > Labels: patch > Attachments: result_detail.png > > > 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. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
