> In coordinator it seems that for Iceberg tables the file descriptors are cached twice. Once for the related HDFS table and once for the Iceberg table. As a solution, for the Iceberg table we should only take care of the Iceberg related part of the file descriptors, and when doing a fromThrift() conversion take the other part of the file descriptor from the Hdfs table.
