@maasg as comment in #21194, I just consider we should not change the 
behavior while `seconds > rampUpTimeSeconds`. Maybe it more important than 
smooth.

Hi Jerry,
There's an improvement from the original situation, but the initial ramp-up 
phase starts only when the time gets very close to `rampUpTime`. Here you have 
another example that shows the behavior:
Above: The original implementation
Below: This PR. (Notebook 
src:https://gist.github.com/maasg/95eab0e49eeef9c7457bca2900bf412e)

This behavior is not consistent with the working, case when `rowsPerSecond 
> rampUpTime`
In this case, the ramp-up is quite smooth:

Isn't this a flat ramp-up smoothly increasing the rows per second? Your 
proposal is another solution, but just two options...

Hi Jerry, 
I don't think the issue is solved with this patch. I plugged the new 
function in my notebook and it still shows a rather flat ramp-up:

I created a PR with an alternative rate computation: 
https://github.com/apache/spark/pull/21194
Could you have a look?
