> When running a query against BigQueryIO with a REPEATED RECORD field the behavior is different between DirectRunner and DataflowRunner. The field containing the repeated record has to be cast to access the records. Apparently the following implementations work for each runner but I would expect them to be the same as my pipeline otherwise only runs on one.
> DirectRunner:
> {code:java}
> ArrayList<LinkedHashMap> orderLines = (ArrayList<LinkedHashMap>) c.element().get("RepeatedField");
> {code}
> DataflowRunner:
> {code:java}
> ImmutableList<TableRow> orderLines = (ImmutableList<TableRow>) c.element().get("RepeatedField");
> {code}
> 				
> For example when using the ImmutableList implementation on DirectRunner the following exception is thrown:
> {code:java}
> java.lang.ClassCastException: java.util.ArrayList cannot be cast to com.google.common.collect.ImmutableList
> {code}
