Xiao Li commented on SPARK-19209:
---------------------------------
I am trying to find a workaround for your case. Could you add an extra option
{{.option("driver", "com.mysql.jdbc.Driver")}} in your code?
Note, I do not have your class name. Could you replace it by your class name in
the option?
> "No suitable driver" on first try

> Simply re-executing the same command a second time "fixes" the {{No suitable
> driver}} error.
> My guess is this is fallout from https://github.com/apache/spark/pull/15292
> which changed the JDBC driver management code. But this code is so hard to
> understand for me, I could be totally wrong.
> This is nothing more than a nuisance for {{spark-shell}} usage, but it is
> more painful to work around for applications.
