> This ticket tracks configurations which need to be renamed, deprecated, or have their defaults changed for Spark 1.5.0.
> Note that subtasks / comments here do not necessarily need to reflect changes that must be performed. Rather, tasks should be added here to make sure that the relevant configurations are at least checked before we cut releases. This ticket will also help us to track configuration changes which must make it into the release notes.
> *Configuration renaming*
> - Consider renaming {{spark.shuffle.memoryFraction}} to {{spark.execution.memoryFraction}} ([discussion|https://github.com/apache/spark/pull/7770#discussion-diff-36019144]).
> - Rename all public-facing uses of {{unsafe}} to something less scary, such as {{tungsten}}
> *Defaults changes*
> - Codegen is now enabled by default.
> - Tungsten is now enabled by default.
> - Parquet schema merging is now disabled by default.
> - In-memory relation partition pruning should be enabled by default (SPARK-9554).
> *Deprecation*
> - Local execution has been removed.
> *Behavior Changes*
> - Canonical name of SQL/DataFrame functions are now lower case (e.g. sum vs SUM)
> - DirectOutputCommitter is not safe to use with speculation
