> when I run tests locally (or on cluster IIRC) there are bunch of ZK-related
> exceptions in Hive log, such as
> {noformat}

> They are annoying when you look for actual problems in logs.
> Those on DEBUG level should be silenced via log levels for ZK classes by
> default. Not sure what to do with ERROR level one(s?), I'd need to look if
> they can be silenced/logged as DEBUG on hive side, or maybe file a bug for
> ZK...
