But one RS only have 3 threads to open region by default. If a > RS have hundreds of regions, the failover is very slower. Assign to same RS > may have good locality if the Datanode is deploied on same host. But slower > failover make the availability worse. And the locality is not big deal when > deploy HBase on cloud. > This was introduced by HBASE-18946. -- This message was sent by Atlassian Jira (v8.3.4#803005)
