Get rid of message: ... waiting for elected master node... to setup local exporter... (does it have x-pack installed?)

How do I shut off this message? I'm using the fully open-source version of ES 7.5.2:
[2020-02-20T00:22:18,086][INFO ][o.e.x.m.e.l.LocalExporter] [coordinator6] waiting for elected master node [{master1}{68sPQmYrRdW60YXSGUeT2w}{q1O7KyfyQyyait5ZuC_ckA}{}{}{ml.machine_memory=2090577920, ml.max_open_jobs=20, xpack.installed=true, ml.enabled=true, zone=primary}] to setup local exporter [default_local] (does it have x-pack installed?)

The version you're using is past EOL, you should upgrade to a supported version. More recent versions don't emit this message.
