Liu Jia updated HBASE-4120: --------------------------- Attachment: TablePriority_v17.patch Simplified the design,remove the thread priority and some complex parts. > isolation and allocation > ------------------------ > > 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, 0.90.3, 0.90.4, 0.92.0 > Reporter: Liu Jia > Assignee: Liu Jia > Fix For: 0.94.0 > > Attachments: Design_document_for_HBase_isolation_and_allocation.pdf, > Design_document_for_HBase_isolation_and_allocation_Revised.pdf, > HBase_isolation_and_allocation_user_guide.pdf, > Performance_of_Table_priority.pdf, > Simple_YCSB_Tests_For_TablePriority_Trunk_and_0.90.4.pdf, System > Structure.jpg, TablePriority.patch, TablePriority_v12.patch, > TablePriority_v12.patch, TablePriority_v15_with_coprocessor.patch, > TablePriority_v16_with_coprocessor.patch, TablePriority_v17.patch, > TablePriority_v8.patch, TablePriority_v8.patch, > TablePriority_v8_for_trunk.patch, TablePrioriy_v9.patch > > > 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. -- This message is automatically generated by JIRA.
