Could not be found for reporter influxdb

Question

I used flink 1.11 but task manager couldn't find org.apache.flink.metrics.influxdb.InfluxdbReporterFactory

WARN  org.apache.flink.runtime.metrics.ReporterSetup               [] - The reporter factory (org.apache.flink.metrics.influxdb.InfluxdbReporterFactory) could not be found for reporter influxdb.

Yes, that's a known bug in Flink 1.11.0: see FLINK-18573.

This will be fixed in 1.11.1. RC1 is open for voting now; see http://apache-flink-mailing-list-archive.1008284.n3.nabble.com/VOTE-Release-1-11-1-release-candidate-1-td43200.html if you want to participate in testing.
