When running distributed warp with influxdb, the app would always hang at the end of each run. This is because the channel used to send operations to Influx isn't used on the initiator process and thus, never gets closed. The app then hangs on the global wait group for the influx goroutine to complete.

--influxdb, the app would always hang at the end of each run. After investigation, it appears this is because the channel used to send operations to Influx isn't used on the master process and thus, never gets closed. The app then hangs on the global wait group waiting for the influx goroutine to complete.As a fix, I closed the
ExtraOutchannels after therunServerBenchmarkcompletes. Alternatively, you could not start the influx channel on the master node.
