vrozov opened a new pull request, #49654: URL: https://github.com/apache/spark/pull/49654
### What changes were proposed in this pull request? 1. Ensure that if relative path is used in `DataStreamWriter`, the path resolution is done on the Spark Driver and is not deferred to Spark Executor. 2. Construct fully qualified path in `DataSource` similar to how it is done for `DataFrameWriter` before it is passed to `FileStreamSink`. 3. Add a check to `FileStreamSink` that asserts that `path` is an absolute path. https://lists.apache.org/thread/ffzwn1y2fgyjw0j09cv4np9z00wymxwv ### Why are the changes needed? To properly support relative paths in structured streaming. The use case mostly applies to single node local Spark cluster. ### Does this PR introduce _any_ user-facing change? The change is only applicable to the use case when relative path is used in `DataStreamWriter`, resulting in data being output to correct directory. No changes are expected for absolute path (the most common production case). ### How was this patch tested? Added new test case to `FileStreamSinkSuite`. ### Was this patch authored or co-authored using generative AI tooling? No -- This is an automated message from the Apache Git Service.
