[GitHub] [hudi] danny0405 commented on issue #7260: [SUPPORT] ClassCastException when use Flink to read array column

   Hi @hbgstc123 , flink 1.13 does not have complete impl for map and array type for parquet, so we copy our own `ColumnarArrayData` in hudi, it seems that there is something wrong when copying the array data here, but i noticed that the `ColumnarArrayData` for flink 1.13.x is final, so there is no way to inherit from it. What we can do is moving the copied `ColumnarArrayData` to a proper package (same as the flink one), but that is also not a perfect solution, the flink clazz may overwide hudi's copy.
