Work Description: nielm commented on pull request #11438: [BEAM-9505]
Remove spurious error message in SpannerIO when streaming.
URL: https://github.com/apache/beam/pull/11438
In some cases, when the bundle is empty, SpannerIO can report an error:
"Sorter should be null here"
This is not fatal, and no data is lost, but this commit will prevent the
error
message from being reported when empty bundles are encounterd.

> -When using DataflowRunner in streaming mode. DoFn.StartBundle is called
> multiple times for the same bundle.-
> -This does not occur with DirectRunner.-
> -This breaks DoFn's which require per-bundle setup and teardown procedures.-
> When a bundle is empty (such as in streaming if a window is empty), SpannerIO
> will report a spurious error message:
> {{IllegalStateException: Sorter should be null here}}
