Description

val customOutputFormat = outbound.select(concat(
outbound.col("device_id"), lit ("\t"),
lit("\"device\"=\""), col("device"), lit("\","),
lit("\"_fd_cast\"=\""), col("_fd_cast"), lit("\",")
).where("device_type='ios_app' and _fd_cast is not null")

customOutputFormat
.limit(1000)
.write
.option("nullValue", "NULL")
.mode("overwrite")
.text("/filepath")

There is no problem writing to JSON, CSV or Parquet. And above code works. As soon as you take out "and _fd_cast is not null" though it throws the exception below. And using either nullValue either treatEmptyValuesAsNulls either reading in or writing out doesn't seem to matter.

Exception is:
