> I'm trying to run a very simple GCP Dataflow SQL job (copy all columns from
> table A to B), and it's failing with the following exception:
> {code:java}
> Caused by: java.lang.ClassCastException: org.apache.avro.util.Utf8 cannot be
> cast to java.lang.Longat
> org.apache.beam.sdk.io.gcp.bigquery.BigQueryUtils.truncateToMillis
> (BigQueryUtils.java:643)at
> org.apache.beam.sdk.io.gcp.bigquery.BigQueryUtils.convertAvroFormat
> (BigQueryUtils.java:597)at
> org.apache.beam.sdk.io.gcp.bigquery.BigQueryUtils.lambda$toBeamRow$5
> (BigQueryUtils.java:389)
> {code}
> It looks to me like this is because BigQueryUtils.convertAvroFormat expects
> that any value whose (beam) type is "DATETIME" must be expressed in unix
> millis. However, these values come out of BigQuery as a string, (AFAICT) in
> ISO 8601 format.
