Enhance the service dashboards in Ambari Web and provide a set of user customizable widgets. To enhance service dashboard, each service will support fully customizable widgets including heatmaps, numbers, gauges and graphs. These widgets should also be added/deleted/sorted/edited by the user along with pre-defined widgets made available by default.
The logic and metadata for rendering these widgets will stored on the Ambari Server and be driven by Stack definitions. The HDP Stack definition (specifically HDFS, YARN and HBase services) will be enhanced to include definitions for service dashboard widgets.
