    Description

      Query the phoenix data using the filter got the NPE (stack error at the Iceberg format module), because the #canImplement(Filter filter) might accept a JDBCTableScan (or an object that extend the TableScan of Calcite), then #getDrillTable(TableScan) will get the null.

      Caused by: java.lang.NullPointerException: null
