German Schiavon Matteo updated SPARK-32158:
-------------------------------------------
Description:
Actually when calling `toJSON` on a dataFrame with null values, it doesn't
print them.
Basically the same idea than https://issues.apache.org/jira/browse/SPARK-23772.
{code:java}
val df = spark.sparkContext.parallelize(Seq("1", "2", null)).toDF("col1")
df.toJSON -> {"col1":"1"},{"col1":"2"},{}{code}
After the PR:
{code:java}
val result = df.toJSON(Map("ignoreNullFields" ->
"false")).collect().mkString(",")
val expected = """{"col1":"1"},{"col1":"2"},{"col1":null}"""
{code}
