Hi, I'm curious why Spark SQL uses two different methods for the seemingly very same code?
* DataFrameWriter.runCommand --> https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/DataFrameWriter.scala#L663 * Dataset.withAction --> https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/Dataset.scala#L3317 It looks like the relationship is as follows: DataFrameWriter.runCommand == Dataset.withAction(_.execute) Should one be removed for the other? I'd first change runCommand to use withAction(_.execute) or even remove runCommand altogether.
