  You need to install the Sedona libraries via init script because the libraries installed via UI are installed after the cluster has already started, and therefore the classes specified by the config `spark.sql.extensions`, `spark.serializer`, and `spark.kryo.registrator` are not available at startup time.*

+### Verify installation

+After you have started the cluster, you can verify that Sedona is correctly installed by running the following code in a notebook:

+spark.sql("SELECT ST_Point(1, 1)").show()

+Note that: you don't need to run the `SedonaRegistrator.registerAll(spark)` or `SedonaContext.create(spark)` in the advanced edition because `org.apache.sedona.sql.SedonaSqlExtensions` in the Cluster Config will take care of that.

 * Please always use the latest version or state the version used in your benchmark so that we can trace back to the issues.
-* Please consider using Sedona core instead of Sedona SQL. Due to the limitation of SparkSQL (for instance, not support clustered index), we are not able to expose all features to SparkSQL.
 * Please open Sedona kryo serializer to reduce the memory footprint.
