> Project: Hadoop Common
> Issue Type: Bug
> Components: fs

> Reporter: Jason Lowe
> Assignee: Hanisha Koneru
> Fix For: 2.9.0, 2.8.3, 2.7.5, 3.0.0

> LoadGenerator#genFile's write close timing code looks like the following:
> {code}
> startTime = Time.now();
> executionTime[WRITE_CLOSE] += (Time.now() - startTime);
> {code}
> That code will generate a zero (or near zero) write close timing since it
> isn't actually closing the file in-between timestamp lookups.
