Description
One feature gap with MR history server is the ability to drill down into counters. A can click on a specific counter in the counter table and see the breakdown across tasks. This is most useful in the DAG counters and vertex counters views to drill down to understand the breakdown of the counter at the level deeper. For example DAG -> Vertex -> Task
As part of discussion with TEZ-2923, we should enhance the AM counter caching since counter drill down can make use of the cache.
