Assignee: Burak Yavuz
> Add flag to stop existing stream when new copy starts
> -----------------------------------------------------
>
> Key: SPARK-29568
> URL: https://issues.apache.org/jira/browse/SPARK-29568
> Project: Spark
> Issue Type: Improvement
> Components: Structured Streaming
> Affects Versions: 3.0.0
> Reporter: Burak Yavuz
> Assignee: Burak Yavuz
> Priority: Major
>
> In multi-tenant environments where you have multiple SparkSessions, you can
> accidentally start multiple copies of the same stream (i.e. streams using the
> same checkpoint location). This will cause all new instantiations of the new
> stream to fail. However, sometimes you may want to turn off the old stream,
> as the old stream may have turned into a zombie (you no longer have access to
> the query handle or SparkSession).
> It would be nice to have a SQL flag that allows the stopping of the old
> stream for such zombie cases.
