Project: Beam

Affects Versions: 2.13.0
Environment: Running on OS X 10.14.5 (18F132), JRE 1.8.0_152, also in

Reporter: Viktor Gerdin
When trying to use BigQueryIO.write() with BigQueryUtils.toTableRow() with a
BYTES field it breaks with
{noformat}
java.lang.ClassCastException: [B cannot be cast to java.nio.ByteBuffer at
org.apache.beam.sdk.io.gcp.bigquery.BigQueryUtils.fromBeamField(BigQueryUtils.java:280){noformat}
BigQueryUtils.fromBeamField() attempts to cast fieldValue to
java.nio.ByteBuffer but it is a byte[].
Unit tests are not covering BYTES field type.
