@liuml07 it's split in hadoop-common API and the changes in S3A, where S3A reworks a lot of the statistics code in general (move to interfaces over single implementations in S3AInstrumentation, using the IOStatistics as the way stats are collected and reported). Yes, it touches a lot of files. Look at #2323 first, as that is what we expect applications to use and for other instrumented bits of code (ABFS) to pick up. FWIW I have a PoC parquet hadoop reader which collects this stuff, that's how I've been seeing how well the API works in practise ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
