Alex Baretta commented on SPARK-5235:
-------------------------------------
[~sowen] My SQL queries are failing due to this. I find it highly unlikely that
I might be unwittingly capturing the SQLContext in my sql("select ....") call.
So, no, the problem cannot be solved by "just not serializing" SQLContext.
