[SPARK-40993][CONNECT][PYTHON][DOCS] Migrate markdown style README to PySpark Development Documentation #49221
Conversation
…o PySpark Development Documentation ### What changes were proposed in this pull request? Added troubleshooting instructions for Spark driver binding issues, including setting `SPARK_LOCAL_IP` to `127.0.0.1` and running Spark shell as a workaround. ### Why are the changes needed? Users may encounter an issue where the Spark driver cannot bind to a random free port, leading to errors during initialization. Providing clear instructions will help users quickly resolve this problem. ### Does this PR introduce any user-facing change? Yes, it adds troubleshooting steps to address Spark driver binding issues. ### How was this patch tested? Manually verified by setting `SPARK_LOCAL_IP` to `127.0.0.1` and running Spark shell. Confirmed that the issue no longer occurs.

I actually don't think this is specific to PySpark but Spark development in general. Since we don't have a page for Spark itself yet, maybe we can add the details into https://spark.apache.org/docs/latest/api/python/development/debugging.html#common-exceptions-errors for now.
It'd be great if we can explain the background and details about why it has to be set, and why it happens.

Yea adding this to debugging.rst would be better, and we have a reference link mentioned in the testing guide.

Let's also file a new JIRA for this, see also https://spark.apache.org/contributing.html |

We're closing this PR because it hasn't been updated in a while. This isn't a judgement on the merit of the PR in any way. It's just a way of keeping the PR queue manageable. |
