> Project: Hive
> Issue Type: Improvement

> Since TEZ-4451, we maintain a thread local snapshot of the IOStatistics in
> TaskRunner2Callable, which can be reused in LLAP (due to its threadlocal
> nature).
> Motivation here: in cloud environments, the stats provided by
> FileSystem.Statistics are not suitable for in-depth debugging, we only have
> bytesRead, bytesWrite and so, and in case of throttling and retries, we don't
> have the chance to tell what led to performance degradation.
> The proposal here is to utilize the IOStatistics already given by Tez to get
> stats like:
