If FE tests hang on your machine, try restarting the minicluster

[Lars Volker]

Hi All,

The frontend tests seemed to hang on my local dev machine. Running jstack
on the child of a hanging test process gave the attached stacks.

>From the stacks it looked like Kudu was implicated in the hang, and a
restart of the local minicluster fixed the issue. Hope it helps someone. :)

Cheers, Lars
