ASF GitHub Bot updated SPARK-53743:
-----------------------------------
Labels: pull-request-available (was: )
> ListState fetchWithArrow option does not work with PySpark Row type API
> -----------------------------------------------------------------------
>
> Key: SPARK-53743
> URL: https://issues.apache.org/jira/browse/SPARK-53743
> Project: Spark
> Issue Type: Bug
> Components: Structured Streaming
> Affects Versions: 4.1.0
> Reporter: Jungtaek Lim
> Priority: Major
> Labels: pull-request-available
>
> We got a report that TWS PySpark with Row type API failed on requesting
> ListState.put(), weirdly ran fine and eventually failed.
> From stack trace of the report, we figured out it took the code path of
> fetchWithArrow (which is only triggered when the list size is exactly 100 -
> which was a bug) and the conversion somehow failed on below stack trace:
> {code:java}

> TypeError: int() argument must be a string, a bytes-like object or a real
> number, not 'NoneType' {code}
> The report stated that they don't have an issue when they workaround to do
> clear() and put element separately (not triggering the path of
> fetchWithArrow).
