----------------------------------
Summary: Create spark context lazily to avoid long startup times
for the kernel
Key: TOREE-299
URL: https://issues.apache.org/jira/browse/TOREE-299
Project: TOREE
Issue Type: Improvement
Reporter: Gino Bustelo
Currently the options are to start or not start a kernel at startup time. The
"not start" option leaves it all to the user.
I propose that when the kernel is managing the spark context, that is starts it
lazily when the user first tries to get a hold of the reference.
I tried to do this as part of https://github.com/apache/incubator-toree/pull/15
but hit some roadblocks that I did not want to tackle as part of that PR.
Now that the `sc`is a `def` it can easily be made lazy.
