Unable to Load Geojson File using Sedona Context in Databricks

[Kunal-Mishra10]

Expected behavior

I am trying to execute the following code in Databricks as mentioned in the Sedona Official Doc

df = sedona.read.format("geojson").option("multiLine", "true").load("PATH/TO/MYFILE.json") .selectExpr("explode(features) as features") # Explode the envelope to get one feature per row. .select("features.*") # Unpack the features struct. .withColumn("prop0", f.expr("properties['prop0']")).drop("properties").drop("type")

df.show() df.printSchema()

Ref : https://sedona.apache.org/latest-snapshot/tutorial/sql/#__tabbed_14_3

I am getting the following error

Caused by: java.lang.NoSuchMethodError: org.apache.spark.sql.execution.datasources.json.JsonDataSource.readFile(Lorg/apache/hadoop/conf/Configuration;Lorg/apache/spark/sql/execution/datasources/PartitionedFile;Lorg/apache/spark/sql/catalyst/json/JacksonParser;Lorg/apache/spark/sql/types/StructType;)Lscala/collection/Iterator;

Actual behavior

geojson file should be loaded into the dataframe

Steps to reproduce the problem

I have installed the following jar files

• geotools-wrapper-1.6.1-28.2.jar
• sedona-spark-shaded-3.4_2.12-1.6.1.jar

I have installed the following libraries

• apache-sedona==1.6.1
• geopandas==0.11.1
• keplergl==0.3.2
• pydeck==0.8.0

Settings

Sedona version = 1.6.1

Apache Spark version = 3.5.0 (Not working with Spark 3.4 Version as well)

Apache Flink version = NA

API type = Scala, Java, Python? Python

Scala version = 2.11, 2.12, 2.13? 2.12

JRE version = 1.8, 1.11? 1.8

Are you using shared access cluster in Databricks?

Copying something Jia said in another thread:

the Shared Access cluster on Databricks does not allow Spark DataSourceV2. This will prevent you from using Sedona GeoJSON reader/writer, GeoParquet reader/writer. Until Databricks fixes this limitation, you won't be able to use these data sources on Databricks Shared access cluster.

Hi James, I am using single user cluster in databricks.

I can confirm that function exists in open source spark with that signature. I wonder if there is some difference in implementation in the databricks json DataSource. @Kontinuation have you been able to test the geojson reader in databricks?

I've reproduced this on DBR 15.4 LTS. The JsonDataSource.readFile method on DBR takes one extra argument, that makes it binary incompatible with the open-source Spark. I've submitted a patch to workaround this: https://github.com/apache/sedona/pull/1662
