[jira] [Commented] (BEAM-4685) Allow writing to time partitioned tables when CreateDisposition==CREATE_NEVER

    [ https://issues.apache.org/jira/browse/BEAM-4685?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16594131#comment-16594131 ] 

Stephen Johnston commented on BEAM-4685:
----------------------------------------

[~chamikara] I think this is solvable by leaving off the partitioning info. It seems this might be an API issue, not a Beam issue. Regardless of the CREATE_DISPOSITION the API performs partitioning validation if it is sent in the job information.

> Writing to time partitioned table fails when CreateDisposition==CREATE_NEVER with error "Table with field based partitioning must have a schema".
> This seems to be due to BigQuery not setting schema for this case.
