Some reasons why Spark 4 is considered experimental (as of August 2025):
-
Missing HBase compatibility (See: https://github.com/apache/hbase-connectors/pull/130)
-
Missing Iceberg compatibility (See: https://github.com/apache/iceberg/issues/13358)
-
Executors fail to load logging libs (maybe related: https://issues.apache.org/jira/browse/SPARK-52585)
