Why is Hive Trying to Replicate?

I've got a new HDP 3.1.0 installation and I've started seeing failures in the hiveserver2.log about replication. Something is trying to run the following command and it isn't me. This is on a completely isolated system that isn't exposed outside of my vpn so I'm not sure what's going on.

repl dump `*` from 71931 with ('hive.repl.dump.metadata.only'='true', 'hive.repl.dump.include.acid.tables'='true')

The failure message is this which I'm assuming is normal because the NOTIFICATION_LOG doesn't keep records forever.

2019-03-24T12:31:17,394 ERROR [HiveServer2-Background-Pool: Thread-209]: metastore.HiveMetaStoreClient (:()) - Requested events are found missing in NOTIFICATION_LOG table. Expected: 71932, Actual: 121582. Probably, cleaner would've cleaned it up. Try setting higher value for hive.metastore.event.db.listener.timetolive. Also, bootstrap the system again to get back the consistent replicated state.

Turns out DAS Lite was trying to dump and failing due to it having been shutdown for too long.
