Note
Note
Hive and Accumulo installed on the same host might result in a potential port conflict because hive.server2.webui.port in hive-site.xml also uses port 10002. To avoid this port conflict, consider installing Hive and Accumulo on different hosts of your cluster.
Master Replication Service Master nodes (Active master and any standby) 10001 Master Thrift service supporting multi-instance Accumulo replication No
