[SPARK-5645] Added local read bytes/time to task metrics
@ksakellis I stumbled on your JIRA for this yesterday; I know it's assigned
to you but I'd already done this for my own uses a while ago so thought I could
help save you the work of doing it! Hopefully this doesn't duplicate any work
you've already done.
Here's a screenshot of what the UI looks like:
Based on a discussion with @pwendell, I put the data read remotely in as an
additional metric rather than showing it in brackets as you'd suggested,
Kostas. The assumption here is that the average user doesn't care about the
differentiation between local / remote data, so it's better not to pollute the
UI.
I also added data about the local read time, which I've found very helpful
for debugging, but I didn't put it in the UI because I think it's probably
something not a ton of people will need to use.
With this change, the total read time and total write time shown in the UI
should now add up properly:
