> Tests report throttling errors in IAM being remapped to noauth and failure
> Again, impala tests, but with multiple processes on same host. this means that HADOOP-18945 isn't sufficient as even if it ensures a singleton instance for a process
> * it doesn't if there are many test buckets (fixable)
> * it doesn't work across processes (not fixable)
> we may be able to 
> * use a singleton across all filesystem instances
> * once we know how throttling is reported, handle it through retries + error/stats collection
