[yt-users] problem running yt in parallel

[Nathan Goldbaum]

Hi Ari,

Thanks for the report! This is a genuine bug, due to a pull request that
was merged just a few days ago that removed the rootLogger.

If you update to the change before the pull request was merged (changeset
hash bca4a05), this issue should go away. Let us know if you need help
updating to the old version.

I've opened an issue to track this:
https://bitbucket.org/yt_analysis/yt/issue/956/enable_parallelism-dies-due-to-missing

If you have a bitbucket account, you can watch the issue to get e-mail
updates.

Hopefully we should have this fixed soon.

-Nathan
