      Description

      Besides wasting resources, this also emits the same log message every second:

      I0108 21:05:07.748235  1443 hms_notification_log_listener.cc:227] Skipping Hive Metastore notification log poll: Illegal state: Not the leader. Local UUID: c77bd888023149729481b7fd041b5c83, Raft Consensus state: current_term: 6 committed_config { opid_index: -1 OBSOLETE_local: false peers { permanent_uuid: "12e9881f0c094a38b83c3b00f71a0ef1" member_type: VOTER last_known_addr { host: "127.0.60.126" port: 43289 } } peers { permanent_uuid: "c77bd888023149729481b7fd041b5c83" member_type: VOTER last_known_addr { host: "127.0.60.125" port: 38761 } } peers { permanent_uuid: "c362d38459074310a6fbd3da10153538" member_type: VOTER last_known_addr { host: "127.0.60.124" port: 34903 } } }
      

      We could throttle the log message, though perhaps the more complete solution is to only activate the log listener in the leader master.
