Yes, that was exactly what was happening. Here is what I had to do to trick
Spark to make the column nullable.
```
from pyspark.sql.functions import col,lit, when
from pyspark.sql import functions as F
incoming_df=incoming_df.withColumn("_hoodie_is_deleted",lit(1)].cast(BooleanType())
incoming_df=incoming_df.withColumn("_hoodie_is_deleted",
when(F.expr("_hoodie_is_deleted is not NULL"),
col("_hoodie_is_deleted")).otherwise(lit(None)))
```
and now the column is nullable and the record is deleted!
```
root
|-- id: long (nullable = true)
|-- sk: long (nullable = true)
|-- txt: string (nullable = true)
|-- partitionKey: string (nullable = true)
|-- year: string (nullable = true)
|-- month: long (nullable = true)
|-- _hoodie_is_deleted: boolean (nullable = true)
```
