[PR] [WIP] Kyuubi Connect [kyuubi]
pan3793 opened a new pull request, #6642:
URL: https://github.com/apache/kyuubi/pull/6642
This is a quick and dirty PR that implements the Spark Connect (gRPC-based) protocol, which allows you to use `pyspark` or `spark-shell` with `remote sc://<host>:<port>` mode to connect Kyuubi and run Spark queries.
DISCLAIMER: this patch is not ready for review, and I know it breaks the existing functionalities, which will be fixed later.
For explorers who want to try this early version:
### Source Code under development
```
git clone https://github.com/pan3793/kyuubi.git -b kyuubi-next kyuubi-next
```
### Requirements
- `JAVA_HOME` points to Java 17
- `SPARK_HOME` points to `/path/of/spark-4.0.0-preview1-bin-hadoop3`
### Run
#### Run within IDEA
- Run `build/mvn clean install -DskipTests` to build the project and produce the Spark engine jar
- Run `kyuubi-server/src/main/scala/org/apache/kyuubi/server/KyuubiServer.scala` using IDEA
You can set `SPARK_HOME`, `KYUUBI_CONF_DIR` in the Run/Debug Configuration Dialog
<img width="912" alt="idea_run_debug_configurations_dialog" src="https://github.com/user-attachments/assets/67544b5a-ea3c-4974-8fd6-b6085e9bca46">
#### Run within Terminal
```
build/dist
cd dist
bin/kyuubi run --conf kyuubi.frontend.grpc.bind.port=10999
```
The gRPC service listens 10999 by default.
### Connect to Kyuubi Connect
Spark Connect Scala client(use the latest `spark-shell` as example)
```
git clone git@github.com:apache/spark.git
cd spark
build/sbt package -Phive
SPARK_PREPEND_CLASSES=1 bin/spark-shell --remote sc://H27212-MAC-01.local:10999 --user_id chengpan --user_name chengpan
```
PySpark Connect client (Requires: Python >=3.9)
```
pip install pyspark-connect==4.0.0.dev1
pyspark --remote sc://H27212-MAC-01.local:10999 --user_id chengpan --user_name chengpan
```
Run examples
```

Does it support running on k8s? How is the Spark app created? As far as I know Spark connect server only support creating in client mode, so it must be different from how we create Kyuubi Spark SQL engine, right?

Review Comment:
this is the only unimplemented method, so uploading artifacts does not work now.
it must be fixed before moving on to the next step.

Hi @pan3793 , is there a way to specify which Spark engine to connect in
```
cd /path/of/spark-4.0.0-preview2-bin-hadoop3
bin/spark-shell --remote sc://H27212-MAC-01.local:10999 --user_id chengpan --user_name chengpan
```
, such as `--engine_id ` or something like that?

Hi @pan3793 What is the protocol between Kyuubi server and KyuubiGrpcEngine, it is the Spark connect protocol or else?
And does this feature rely on Spark connect server? Can a user connect to Spark's 15002 port directly?

Thanks for the PR! This PR is being closed due to inactivity. This isn't a judgement on the merit of the PR in any way. If this is still an issue with the latest version of Kyuubi, please reopen it and ask a committer to remove the Stale tag!
Thank you for using Kyuubi!
