I believe this is caused by the HadoopFileIO [no-arg constructor](https://github.com/apache/iceberg/blob/01393a06c284175edab75de34f48b2bfbd606081/core/src/main/java/org/apache/iceberg/hadoop/HadoopFileIO.java#L42) not setting an empty conf. Using the `HadoopFileIO` directly you can use `setConf` to add an empty configuration (when reading local files) and the NPE goes away. Should the no-arg constructor do the same? ```java public HadoopFileIO() { Configuration conf = new Configuration(); this.hadoopConf = new SerializableConfiguration(conf)::get; } ``` Otherwise, is there some other way to set an empty conf before `JdbcCatalog` uses it? -- This is an automated message from the Apache Git Service.
