Just built master, got all of the artifacts ready, blah blah blah. Tested by installing the artifact from https://dist.apache.org/repos/dist/dev/incubator/toree/0.1.0/rc5/toree-pip/ and now it's failing with not being able to bind to an ephemeral port for the sparkDriver. Can someone help me take a look at this? I just installed like usual via `pip install apache-toree-0.1.0.tar.gz` and pointed to spark distributions I downloaded (1.6.1 and 1.6.3) when running `jupyter toree install --spark_home=...`. When launching a kernel, it fails with...
