Jeffrey Zhong commented on HBASE-11059: --------------------------------------- This is great! The result of improvement is terrific. Let me to take a look at this patch. Does this JIRA depend on master colocating meta otherwise meta recovery needs some bootstrap? Thanks. Another idea on this topic is to let RS do all the assignments including meta update and master only need to initiate assignment request & monitor un-assignment regions without even keeping internal memory state. > ZK-less region assignment > ------------------------- > > Key: HBASE-11059 > URL: https://issues.apache.org/jira/browse/HBASE-11059 > Project: HBase > Issue Type: Improvement > Components: master, Region Assignment > Reporter: Jimmy Xiang > Assignee: Jimmy Xiang > Fix For: 0.99.0 > > Attachments: hbase-11059.patch, hbase-11059_v2.1.patch, > hbase-11059_v2.patch, zk-less_am.pdf > > > It seems that most people don't like region assignment with ZK (HBASE-5487), > which causes many uncertainties.
