Ivan Sadikov updated SPARK-40646:
---------------------------------
Description:
I recently found an issue when parsing the following JSON file:
{code:java}
{"a": {"x": 1, "y": true}, "b": {"x": 1}}
{"a": {"x": 2}, "b": {"x": 2}}{code}
Trying to read such table with fixed schema where {{y}} is a struct column and
not a boolean:
{code:java}
val df = spark.read
.schema("a struct<x: int, y: struct<x: int>>, b struct<x: int>")
.json("path") {code}
results in the following answer:
{code:java}
a b
null null
{"x":2,"y":null} {"x":2} {code}
> Fix returning partial results in JSON data source and JSON functions
