HyukjinKwon opened a new pull request, #46295:
URL: https://github.com/apache/spark/pull/46295
### What changes were proposed in this pull request?
This PR proposes to warn that `samplingRatio` and `verifySchema` are not
supported with Spark Connect.
### Why are the changes needed?
For better compatibility in Spark Connect.
### Does this PR introduce _any_ user-facing change?
Yes, it shows a warning to the end users when they use those. For now, it
complains that there's no such argument that `createDataFrame` can take.
### How was this patch tested?
Manually tested as below:
```bash
bin/pyspark --remote local
```
```python
>>> spark.createDataFrame([1,2,3], samplingRatio=0.5)
/.../pyspark/sql/connect/session.py:416: UserWarning: 'samplingRatio' is
ignored. It is not supported with Spark Connect.
warnings.warn("'samplingRatio' is ignored. It is not supported with Spark
Connect.")
DataFrame[_1: bigint]
>>> spark.createDataFrame([1,2,3], verifySchema=True)
/.../pyspark/sql/connect/session.py:419: UserWarning: 'verifySchema' is
ignored. It is not supported with Spark Connect.
warnings.warn("'verifySchema' is ignored. It is not supported with Spark
Connect.")
DataFrame[_1: bigint]
>>> spark.createDataFrame([1,2,3])
DataFrame[_1: bigint]
```
### Was this patch authored or co-authored using generative AI tooling?
No.
