The schema given below creates the issue, as @vdiravka pointed int96 is
marked required here. This parquet was generated with an older version of spark
and is included in the test case.
```
message spark_schema {
optional binary article_no (UTF8);
optional binary qty (UTF8);
required int96 run_date;
}
```
Newer spark version created the schema below where int96 has become
optional.
```
message spark_schema {
optional binary country (UTF8);
optional double sales;
optional int96 targetDate;
}
```
