> grafana is not showing any data points if the queue name contains special
> characters
> I have a queue named 'A&B' , in Yarn queues dashboard if I select this queue
> name I am getting empty data showing no data points.
> The issue is reproducible
> Analysis :
> In grafana UI we are sending the request to fetch the data by encoding the
> URI.
> for which the server is interpreting it as separate parameters
> http://mygrafanaserver.com:3000/api/datasources/proxy/1/ws/v1/timeline/metrics?metricNames=yarn.QueueMetrics.Queue=root.{color:red}A&B{color}.AppsRunning._max&appId=resourcemanager&startTime=1533181180&endTime=1533202780
> Which should ideally be :
> http://mygrafanaserver.com:3000/api/datasources/proxy/1/ws/v1/timeline/metrics?metricNames=yarn.QueueMetrics.Queue=root.{color:red}A%26B{color}.AppsRunning._max&appId=resourcemanager
