You could use `config.hasPath` instead of relying on matching on an empty
string.
> Allow drillbits to advertise a configurable host address to Zookeeper
> ---------------------------------------------------------------------

> Key: DRILL-4935
> URL: https://issues.apache.org/jira/browse/DRILL-4935
> Project: Apache Drill
> Issue Type: New Feature
> Components: Execution - RPC
> Affects Versions: 1.8.0
> Reporter: Harrison Mebane
> Priority: Minor
> Fix For: Future
>
>
> There are certain situations, such as running Drill in distributed Docker
> containers, in which it is desirable to advertise a different hostname to
> Zookeeper than would be output by INetAddress.getLocalHost(). I propose
> adding a configuration variable 'drill.exec.rpc.bit.advertised.host' and
> passing this address to Zookeeper when the configuration variable is
> populated, otherwise falling back to the present behavior.
