Hi Devs, We recently enabled WebHDFS on Hadoop 2.6.0. I couldn't find any traces of metrics in code/documentation for WebHDFS. I feel we need to expose some metrics that may help in debugging/identifying some problems.
*Thoughts on this please?* Here is a quick compilation of metrics to start with - Total requests count - Failed requests count - Success request count - Total Request count by type (GET, POST, CREATE, etc.,) - Failed Request count by type (GET, POST, CREATE, etc.,) - Success request count by response type (OK - 200, REDIRECT - 307, etc.,) - Total bytes read - Total bytes written I can work on this feature if someone else finds this useful. -- Thanks, Laxman
