[GitHub] [hadoop] steveloughran commented on pull request #2145: HADOOP-17133. Implement HttpServer2 metrics

URL: https://github.com/apache/hadoop/pull/2145#issuecomment-661310541


   BTW, on the topic of metrics and HttpFS, look at #2069 . That's adding the ability of client-side code to collect stats exclusive for the specific operation (input stream, output stream, listLocatedStatus) with the integration with the core IO classes so that things pass through all the way. 
   
   Ultimate Goal: a hive/spark/impala job will be able to report an aggregate summary of the IO operations performed during a query, ideally even including throttling/retry events. Nowhere near that level of collection yet, but the public API should be ready for review.
