Description

Below links are throwing HTTP 500:

http://<host>:6188/ws/v1/timeline/metrics?appId=nimbus&hostname=&metricNames=topology.streamline-1-simple-yelp-review.3-SINK.%25.--fail-count.%25&startTime=1522734868701&endTime=1522736668701

http://<host>:3000/api/datasources/proxy/1/ws/v1/timeline/metrics?metricNames=topology.streamline-1-simple-yelp-review.%.--fail-count.%._avg&appId=nimbus&startTime=1522715768&endTime=1522737368&seriesAggregateFunction=sum

Please note that such kind of metrics are not in metadata, but I guess we are returning empty map here, not throwing HTTP 500.
