Description

When installing Druid the `druid.emitter.ambari-metrics.hostname` property is set to the first character of the hostname of the AMS collector host even though the property in Ambari is set to `metric_collector_host`. 

/etc/druid/conf/_common/common.runtime.properties file contains:

druid.emitter=ambari-metrics
druid.emitter.ambari-metrics.eventConverter={"type":"whiteList"}
druid.emitter.ambari-metrics.hostname=c
druid.emitter.ambari-metrics.port=6188
druid.emitter.ambari-metrics.protocol=https
druid.emitter.ambari-metrics.trustStorePassword=clientTrustStorePassword
druid.emitter.ambari-metrics.trustStorePath=/etc/security/clientKeys/all.jks
druid.emitter.ambari-metrics.trustStoreType=jks
