Aaronx-Gallagher opened a new issue, #9302: URL: https://github.com/apache/seatunnel/issues/9302
### Search before asking - [x] I had searched in the [issues](https://github.com/apache/seatunnel/issues?q=is%3Aissue+label%3A%22bug%22) and found no similar issues. ### What happened I set the parallelism to 5 in env and set the parallelism to 1 in Source. However, the result shows that the parallelism has not been changed to 1, but remains at 5. Is this a bug, or am I using it incorrectly?  This is mentioned on the page Source Common Options in the official documentation.  Then I continued to experiment with Doris and Fakesource, but this parameter still had no effect. I found the relevant parallelism settings in the code, and it seems that this does not read from the Source, but only reads from the Env.  ### SeaTunnel Version the seatunnel version is 2.3.10; ### SeaTunnel Config ```conf env{ parallelism = 5 job.mode = "BATCH" spark.master=local } source { Http { parallelism = 1 plugin_output = "http" url = "http://localhost:8083/ttt/testhttp"; method = "GET" format = "json" schema = { fields { msg = string } } } } transform{ } sink{ Console = { plugin_input = "http" } } ``` ### Running Command ```shell I run it in SeaTunnelApiExample.class. ``` ### Error Exception ```log Caused by: java.lang.IllegalArgumentException: A single split source allows only one single reader to be created. Please make sure source parallelism = 1 at org.apache.seatunnel.shade.com.google.common.base.Preconditions.checkArgument(Preconditions.java:141) at org.apache.seatunnel.connectors.seatunnel.common.source.AbstractSingleSplitSource.createReader(AbstractSingleSplitSource.java:34) at org.apache.seatunnel.connectors.seatunnel.common.source.AbstractSingleSplitSource.createReader(AbstractSingleSplitSource.java:28) at org.apache.seatunnel.translation.source.ParallelSource.<init>(ParallelSource.java:106) ... 30 more ``` ### Zeta or Flink or Spark Version _No response_ ### Java or Scala Version _No response_ ### Screenshots _No response_ ### Are you willing to submit PR? - [ ] Yes I am willing to submit a PR! ### Code of Conduct - [x] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
