Description
If the response for Host metrics from rrd.py (Ganglia metrics) contains an empty response for a Ganglia cluster type, the empty response may overwrite valid metrics. For example, if a host has only slave components it may still produce an empty rrd file for HDPNameNode. If it exists, the empty results may overwrite the valid results from the HDPSlaves rrd files.
