Hello, flink=1.20.0 iceberg=1.8.1 If you get the error: ```text Caused by: java.lang.ClassCastException: class org.apache.iceberg.shaded.org.apache.parquet.schema.MessageType cannot be cast to class org.apache.parquet.schema.MessageType (org.apache.iceberg.shaded.org.apache.parquet.schema.MessageType and ``` I faced the same issue during my Flink Iceberg deployment because both iceberg-flink-1.20 and iceberg-flink-runtime-1.20 JARs were present in my Flink cluster at the same time. After I removed the iceberg-flink-1.20 JAR and only kept iceberg-flink-runtime-1.20, the error disappeared! ```text wget -q https://repo1.maven.org/maven2/org/apache/iceberg/iceberg-flink-runtime-1.20/$ICEBERG_VERSION/iceberg-flink-runtime-1.20-$ICEBERG_VERSION.jar -P $FLINK_LIB_DIR # wget -q https://repo1.maven.org/maven2/org/apache/iceberg/iceberg-flink-1.20/$ICEBERG_VERSION/iceberg-flink-1.20-$ICEBERG_VERSION.jar -P $FLINK_LIB_DIR ``` -- This is an automated message from the Apache Git Service.
