Jonathan Turner Eagles commented on TEZ-4026:
---------------------------------------------
[~abstractdog], can you review this simple patch. Essentially, if fetch time is
zero milliseconds we show download rate as 0.0 MB/s. This patch assumes each
fetch takes at least 1 millisecond, which will show slightly slower download
rates than actual, but is a more accurate than 0.0MB/s.
> Fetch Download rate shows 0.0 MB per second if duration is 0 millis

> I think it will be more accurate to assume 1 millisecond so that the download
> rate is more accurate. The other way is to use a more accurate timer, but I
> think that is out of scope for this jira.
