---------------------------------
Summary: Python Streaming job failing to drain with BigQueryIO
write errors
Key: BEAM-14146
URL: https://issues.apache.org/jira/browse/BEAM-14146
Project: Beam
Issue Type: Bug
Components: io-py-gcp, sdk-py-core
Affects Versions: 2.37.0
Reporter: Rahul Iyer
We have a Python Streaming Dataflow job that writes to BigQuery using the
{{FILE_LOADS}} method and {{auto_sharding}} enabled. When we try to drain the
job it fails with the following error,
{code:python}
"/usr/local/lib/python3.7/site-packages/apache_beam/io/gcp/bigquery_tools.py",
line 1000, in perform_load_job ValueError: Either a non-empty list of
fully-qualified source URIs must be provided via the source_uris parameter or
an open file object must be provided via the source_stream parameter.
{code}
Our {{WriteToBigQuery}} configuration,
{code:python}
beam.io.WriteToBigQuery(
table=options.output_table,
schema=bq_schema,
create_disposition=beam.io.BigQueryDisposition.CREATE_IF_NEEDED,
write_disposition=beam.io.BigQueryDisposition.WRITE_APPEND,
insert_retry_strategy=RetryStrategy.RETRY_ON_TRANSIENT_ERROR,
method=beam.io.WriteToBigQuery.Method.FILE_LOADS,
additional_bq_parameters={
"timePartitioning": {
"type": "HOUR",
"field": "bq_insert_timestamp",
},
"schemaUpdateOptions": ["ALLOW_FIELD_ADDITION", "ALLOW_FIELD_RELAXATION"],
},
triggering_frequency=120,
with_auto_sharding=True,
)
{code}
