samredai opened a new issue #4410:
URL: https://github.com/apache/iceberg/issues/4410
When using the `HadoopFileIO` with a `JdbcCatalog`, creating a table runs
into a NPE:
```java
import org.apache.iceberg.catalog.Catalog;
import org.apache.iceberg.CatalogProperties;
import org.apache.iceberg.jdbc.JdbcCatalog;
import org.apache.iceberg.hadoop.HadoopFileIO;
import org.apache.iceberg.catalog.TableIdentifier;
import org.apache.iceberg.Schema;
import org.apache.iceberg.types.Types;
Map<String, String> properties = new HashMap<>();
properties.put(CatalogProperties.CATALOG_IMPL, JdbcCatalog.class.getName());
properties.put(CatalogProperties.URI,
"jdbc:postgresql://postgres:5432/demo_catalog");
properties.put(JdbcCatalog.PROPERTY_PREFIX + "user", "admin");
properties.put(JdbcCatalog.PROPERTY_PREFIX + "password", "password");
properties.put(CatalogProperties.WAREHOUSE_LOCATION,
"/home/iceberg/warehouse");
properties.put(CatalogProperties.FILE_IO_IMPL, HadoopFileIO.class.getName());
Catalog catalog = new JdbcCatalog();
catalog.initialize("demo", properties);
TableIdentifier name = TableIdentifier.of("somedb", "sometable");
Schema schema = new Schema(
Types.NestedField.required(1, "level", Types.StringType.get()),
Types.NestedField.required(2, "event_time",
Types.TimestampType.withZone()),
Types.NestedField.required(3, "message", Types.StringType.get()),
Types.NestedField.optional(4, "call_stack", Types.ListType.ofRequired(5,
Types.StringType.get()))
);
catalog.createTable(name, schema)
```
output:
```java
java.lang.NullPointerException: null
