I'm not sure if I follow the entire discussion here yet. I did spend a
while trying to figure out if there is a race condition, and I'm pretty sure
there is not. From your last comments, it looks like there is a bug in zepplin
for not correctly ensuring that authentication is enabled on the java gateway,
and as @HyukjinKwon indicates, perhaps a bug in spark for not failing more
obviously.
I dont' think I understand this:
> auto token should be set to use Spark
what "auto token" are you referring to?
We should be able to support creating the java gateway inside zepplin, I
think its conceptually the same as what is done when you launch a pyspark
shell. Probably zepplin should be doing something like this:
