Hive LLAP - Heatmap
The heat map shows all the nodes that are running LLAP daemons with percentage summary for available executors and cache. This dashboard lets you identify the hotspots in the cluster in terms of executors and cache.
NOTE: The values in the table are color coded based on threshold: if the threshold is more than 50%, it is Green; 20-50%, it is Yellow; less than 20%, it is Red.
