-----------------------------------------
Summary: Empty file for the first partition
Key: SPARK-33025
URL: https://issues.apache.org/jira/browse/SPARK-33025
Project: Spark
Issue Type: Bug
Components: Spark Core, SQL
Affects Versions: 3.0.1
Reporter: Evgenii Samusenko
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.
