>          Issue Type: Bug
>          Components: io-java-gcp
>    Affects Versions: 2.2.0, 2.3.0
>         Environment: Dataflow streaming pipeline
>            Reporter: Benjamin BENOIST

> My workflow : KAFKA -> Dataflow streaming -> BigQuery
> Given that having low-latency isn't important in my case, I use FILE_LOADS to 
> reduce the costs. I'm using _BigQueryIO.Write_ with a _DynamicDestination_, 
> which is a table with the current hour as a suffix.
> This _BigQueryIO.Write_ is configured like this :
> {code:java}
> .withCreateDisposition(CreateDisposition.CREATE_IF_NEEDED)
> .withMethod(Method.FILE_LOADS)
> .withTriggeringFrequency(triggeringFrequency)
> .withNumFileShards(100)
> {code}
> The first table is successfully created and is written to. But then the 
> following tables are never created and I get these exceptions:
> {code:java}
> (99e5cd8c66414e7a): java.lang.RuntimeException: Failed to create load job 
> with id prefix 
> 5047f71312a94bf3a42ee5d67feede75_5295fbf25e1a7534f85e25dcaa9f4986_00001_00023,
>  reached max retries: 3, last failed load job: {
>   "configuration" : {
>     "load" : {
>       "createDisposition" : "CREATE_NEVER",
>       "destinationTable" : {
>         "datasetId" : "dev_mydataset",
>         "projectId" : "myproject-id",
>         "tableId" : "mytable_20180302_16"
>       },
> {code}
> The _CreateDisposition_ used is _CREATE_NEVER_, contrary as 
> _CREATE_IF_NEEDED_ as specified.
