Kristin Cowalcijk created SEDONA-258:
----------------------------------------
Summary: Cannot directly assign raw spatial RDD to CircleRDD using
Python binding
Key: SEDONA-258
URL: https://issues.apache.org/jira/browse/SEDONA-258
Project: Apache Sedona
Issue Type: Bug
Affects Versions: 1.3.1
Environment: Apache Sedona master branch, Spark version: 3.3.1
Reporter: Kristin Cowalcijk
The following code raises a {{SerializationException}}:
{code:python}
input_location = 'data/arealm-small.csv'
point_rdd = PointRDD(sc, input_location, 1, FileDataSplitter.CSV, True, 1,
StorageLevel.MEMORY_ONLY)
circle_rdd = CircleRDD(point_rdd, 1.0)
circle_rdd_2 = CircleRDD(point_rdd, 2.0)
circle_rdd_2.rawSpatialRDD = circle_rdd.rawSpatialRDD
circle_rdd_2.analyze()
{code}
The stack trace is as follows:

We found that the deserialization code for {{Circle}} objects in python-adapter
does not match with the serialization code, which caused this problem.
