[GitHub] [spark] huanliwang-db opened a new pull request, #40306: [SPARK-42687][SS] Better error message for the unsupport `pivot` operation in Streaming
huanliwang-db opened a new pull request, #40306:
URL: https://github.com/apache/spark/pull/40306
`pivot` is an unsupported operation in structured streaming but produces a bad error message that is quite misleading.
The following is the current error message for the pivot in SS:
```
AnalysisException: Queries with streaming sources must be executed with writeStream.start();
```
We should report that an unsupported operation is happening instead of stating another operation should start the stream.
