> Project: Spark
> Issue Type: Bug
> Components: Spark Core, SQL

> If I create Dataframe with 1 row, Spark will create empty file for the first
> partition.
>
> Example:
> val df = Seq(1).toDF("col1").repartition(8)
> df1.write.csv("/csv")
>
> I got 2 files. The first contains the first partition and the second contains
> single row from another partition. It is valid also for parquet, text and etc.
