-------------------------------------
Summary: Temporal Host metrics can get overwritten.
Key: AMBARI-4394
URL: https://issues.apache.org/jira/browse/AMBARI-4394
Project: Ambari
Issue Type: Bug
Reporter: Tom Beerbower
Assignee: Tom Beerbower
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.
