> BigQueryIO result different for REPEATED field between DirectRunner and
> DataflowRunner
> --------------------------------------------------------------------------------------

> Key: BEAM-2767
> URL: https://issues.apache.org/jira/browse/BEAM-2767
> Project: Beam
> Issue Type: Bug
> Components: io-java-gcp, runner-dataflow, runner-direct
> Affects Versions: 2.0.0
> Reporter: Andre
> Assignee: Udi Meiri
> Priority: P3
> Labels: stale-assigned
>
> 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}
