[jira] [Created] (BEAM-10792) ReadFromBigQuery fails with ValueProvider for table

Michael Ballou created BEAM-10792:
-------------------------------------

             Summary: ReadFromBigQuery fails with ValueProvider for table
                 Key: BEAM-10792
                 URL: https://issues.apache.org/jira/browse/BEAM-10792
             Project: Beam
          Issue Type: Bug
          Components: sdk-py-core
    Affects Versions: 2.23.0
            Reporter: Michael Ballou


2 errors are present:

1. ReadFromBigQuery passing a ValueProvider for the table param gets this error:

'_CustomBigQuerySource' object has no attribute 'dataset'

File "./lib/python3.7/site-packages/apache_beam/io/gcp/bigquery.py", line 656, in estimate_size self.table_reference.get(), self.dataset, self.project)

There are a 2 places where self.dataset are referenced, but it is never set to any value in the CustomBigQuerySource class.  This should be set __init__() method.

2. _export_files references table_ref as a str before checking if its a ValueProvider.
