Kristin Cowalcijk created SEDONA-580:
----------------------------------------
Summary: New instances of RasterUDT object is not equal to the
RasterUDT case object
Key: SEDONA-580
URL: https://issues.apache.org/jira/browse/SEDONA-580
Project: Apache Sedona
Issue Type: Bug
Affects Versions: 1.6.0
Reporter: Kristin Cowalcijk
This issue is similar to
[SEDONA-20|https://issues.apache.org/jira/browse/SEDONA-20]. We have
encountered errors caused by this when working with datasets aggregated using
RS_Union_Aggr. The {{ExpressionEncoder}} will create new instances of
registered UserDefinedType classes, so we have to make sure that such newly
created instances are the same type as the RasterUDT case object, otherwise
we'll see strange SQL analyze exceptions and type mismatches.
We also found that the implementation of GeometryUDT.hashCode is not correct:
objects that are equal with each other has different hash values. Although this
is not causing problems for now but we'd better fix it.
