bsglz edited a comment on issue #1007: HBASE-22639 Unexpected split when a big table has only one region on … URL: https://github.com/apache/hbase/pull/1007#issuecomment-572843885 > The RS is asking the Master how many Regions in a table? Yeah > We do not want the RegionServers harrassing Master with random queries. > Doesn't the RS ask the Master if it can split currently? Can you not have the Master say not split if only one Region in table? The other way is through heartbeat to get this info ,but may be some delay. IMO, if some tasks of RS want to be done reasonable, they need global info unavoidable, such as split region or split log(get lastFlushedSequenceId from master)
