I installed toree with the following command in my Ubuntu 16.04 system:
$ pip install --pre toree
$ jupyter toree install --interpreters=Scala,PySpark,SQL
Then I checked the kernel list. I got kernels installed succussfully:
$ jupyter kernelspec list
Then I start jupyter, here comes the question: Both apache_toree_scala and apache_toree_pyspark kernel will run in error "timeout" when I create a new notebook using that kernel. Here is the error message:
Timeout waiting for kernel_info reply from d98705f0-4bba-4c69-af7f-da99379219f5
My ubuntu was installed in VirtualBox. But I think this shouldn't be a problem.
