Gino Bustelo commented on TOREE-299:
------------------------------------
I think we should try to do this for 0.1.0 because the slow start time reflects
poorly.
> 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
> Fix For: 0.1.0
>
>
> 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.
