Kay Ousterhout commented on SPARK-1466:
---------------------------------------
[~pwendell] I didn't merge this into the 1.0 branch since it's pretty minor and
I don't know if anyone besides the students in the course where we used iPython
notebook have noticed this. I know it was marked as a blocker but I think that
was an inflated priority -- anyway let me know if you think it should go in for
1.0.1.
> Pyspark doesn't check if gateway process launches correctly
> -----------------------------------------------------------
>
> Key: SPARK-1466
> URL: https://issues.apache.org/jira/browse/SPARK-1466
> Project: Spark
> Issue Type: Bug
> Components: PySpark
> Affects Versions: 0.9.0, 0.9.1
> Reporter: Kay Ousterhout
> Assignee: Kay Ousterhout
> Priority: Blocker
> Fix For: 1.1.0
>
>
> If the gateway process fails to start correctly (e.g., because JAVA_HOME
> isn't set correctly, there's no Spark jar, etc.), right now pyspark fails
> because of a very difficult-to-understand error, where we try to parse stdout
> to get the port where Spark started and there's nothing there. We should
> properly catch the error, print it to the user, and exit.
