I've found two places so far where the operation logs are being used:
- Ambari Hive View -> Logs tab normally displays output like the number of mappers/reducers.
- After disabling operation logging the log tab displays nothing.
- Beeline connections -> After executing a query normally some output is displayed.
- After disabling operation logging there is no output except the results of the query.
Would be nice to get these back without compromising hiveserver2!
