Solution is incorrect. We have to provide explicit type for PCollection. This does not work (from solution code). ``` lines.apply("ParseJson", ParDo.of(new JsonToCommonLog())) .apply("DropFields", DropFields.fields("user_agent")) ... ``` This works. ``` PCollection<CommonLog> logs = lines.apply("ParseJson", ParDo.of(new JsonToCommonLog())); logs.apply("DropFields", DropFields.fields("user_agent")) ... ```
