URL: https://github.com/apache/sedona/issues/2608
I am getting weird behavior trying to write a DataFrame containing the
`raster` type to a delta table. The bare `raster` type fails to write,
throwing: `java.lang.NoSuchMethodException:
org.apache.spark.sql.sedona_sql.UDT.RasterUDT$.<init>()`
```python
from sedona.spark import *
sedona = SedonaContext.create(spark)
ras = sedona.sql("SELECT RS_MakeEmptyRaster(1, 'D', 10, 10, 0, 0, 1, -1, 0,
0, 0) as raster")
ras.write.format("delta").save("/tmp/ras")
```
- Throws the exception
```python
ras2 = sedona.sql("SELECT RS_Union_Aggr(RS_MakeEmptyRaster(1, 'D', 10, 10,
0, 0, 1, -1, 0, 0, 0), 0) as raster")
ras2.write.format("delta").save("/tmp/ras2")
```
- Writes without issue
- Loads without any signs of corruption
```python
ras3 = sedona.read.load("/tmp/ras")
ras3.selectExpr(
"explode(RS_PixelAsPoints(raster, 1)) as exploded"
).selectExpr(
"exploded.geom as geom",
"exploded.value as value",
"exploded.x as x",
"exploded.y as y"
).show()
```
Behavior is identical on both
```
Databricks 17.3 LTS + Sedona 1.8.1
Databiricks 16.4 LTS + Sedona 1.7.1
```
with and without the Kryo config
```
spark.serializer org.apache.spark.serializer.KryoSerializer
spark.kryo.registrator org.apache.sedona.core.serde.SedonaKryoRegistrator
```
Any assistance would be greatly appreciated, and happy to provide additional
information as necessary. Thanks!
