An example roll:

https://codereview.chromium.org/2617703005

Failure log:
https://chromium-swarm.appspot.com/task?id=338cb4158a241110&refresh=10&show_raw=1


Almost all of these failures are due to certain files or directory are missing. So I am suspecting this is infra failure. May this has something to do with the swarming bot's hard disk is full?


The failures are:
