   hi,
   trying to enable emitters on my historical nodes with the following configuration:
   
   ```
   #Enabling Metrics
   druid.monitoring.emissionPeriod=PT1M
   druid.monitoring.monitors=["org.apache.druid.client.cache.CacheMonitor","org.apache.druid.server.metrics.HistoricalMetricsMonitor","org.apache.druid.java.util.metrics.JvmMonitor","org.apache.druid.java.util.metrics.JvmCpuMonitor","org.apache.druid.server.metrics.QueryCountStatsMonitor"]# Emitting Metrics
   druid.emitter=http
   druid.emitter.composing.emitters=["http"]
   druid.emitter.logging.logLevel=info
   druid.emitter.http.recipientBaseUrl=http://druid-realtime1.com:8085/v1/post/metrics
   ```
   
   getting the following errors -
   on historical:
   
   ```
   ERROR [HttpPostEmitter-1] org.apache.druid.java.util.emitter.core.HttpPostEmitter - Failed to send events to url[http://druid-realtime1.splicky.com:8085/v1/post/metrics]
   ERROR [HttpPostEmitter-1] org.apache.druid.java.util.emitter.core.HttpPostEmitter - Timing out emitter batch send, last batch fill time [32] ms, timeout [64] ms
   ```
   
   on tranquility (the realtime node):
   
   ```
   WARN  c.m.t.server.http.TranquilityServlet - Server error serving request to http://druid-realtime1.splicky.com:8085/v1/post/metrics
   Early EOF (through reference chain: com.fasterxml.jackson.module.scala.deser.MapBuilderWrapper["interval"]->com.fasterxml.jackson.module.scala.deser.BuilderWrapper[0])
   ```
   
   any help will be appreciated,
   Thanks!
