"[DISCUSS] No regions on Master node in 2.0" is one thread that talks about this topic with attached docs that discuss pros and cons. Y! production is running a hacked hbase that splits hbase:meta. They are trying to get the facility back upstream ([~toffer] FYI). The new AM is doing its best to support splittable hbase:meta. More work to do. A patch that makes an argument that hbase:acl should not split because hbase:meta does not split is specious and going in the wrong direction. > Make hbase:acl table unsplittable > --------------------------------- > > Key: HBASE-16803 > URL: https://issues.apache.org/jira/browse/HBASE-16803 > Project: HBase > Issue Type: Improvement > Reporter: Ted Yu > Assignee: Ted Yu > Attachments: 16803.v1.txt, 16803.v2.txt > > > HBASE-16773 fixed a case where PriorityRpcServer handler threads are all occupied accessing hbase:acl table. > However, the fix relies on the fact that there is single region in hbase:acl table so that the access can be local. > As discussed at the end of HBASE-16773, we should disable split of hbase:acl table as well. > hbase:meta is normally much larger than hbase:acl table and it has only one region. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
