> With JDBC server, set Kryo as default serializer and disable reference
> tracking
> -------------------------------------------------------------------------------

> Key: SPARK-4761
> URL: https://issues.apache.org/jira/browse/SPARK-4761
> Project: Spark
> Issue Type: Bug
> Reporter: Patrick Wendell
> Assignee: Cheng Lian
> Priority: Blocker
> Fix For: 1.2.0
>
>
> I saw some regression in 1.2 Spark SQL due to our broadcast change which
> requires significantly more serialization. It would be good if when the JDBC
> server is running it automatically sets the serializer to Kryo and disables
> Kryo reference tracking.
> Doing this while still honoring a user-provided serializer is tricky. I think
> the best way is to expose an internal (private) constructor to SparkConf that
> takes a set of lowest-precedence defaults. Those could get merged in with the
> lowest precedence before the config file is read.
