   > the community is trying to use Parquet 1.12 to enable PME
   
   > Our re-shading of org.codehaus.jackson breaks Parquet encryption
   
   Some clarification. According to the current design draft in the community, Iceberg will use a part of PME in Parquet-1.12 - the part that implements the spec, and doesn't need the codehaus jackson (or any other json lib). The other part, that implements a Parquet version of key management, will not be used, because Iceberg will have project-wide modules with encryption API and key management that work the same for Parquet, ORC, Avro data files and for all metadata files. Only these modules will need a json lib; Iceberg will be free from PME key manager dependency on codehaus jackson.
