# Debugging Kyuubi
|
|
|
|
You can use the [Java Debug Wire Protocol](https://docs.oracle.com/javase/8/docs/technotes/guides/jpda/conninv.html#Plugin) to debug Kyuubi
|
|
with your favorite IDE tool, e.g. IntelliJ IDEA.
|
|
|
|
## Debugging Server
|
|
|
|
We can configure the JDWP agent in `KYUUBI_JAVA_OPTS` for debugging.
|
|
|
|
|
|
For example,
|
|
```bash
|
|
KYUUBI_JAVA_OPTS=-agentlib:jdwp=transport=dt_socket,server=y,suspend=y,address=5005 \
|
|
bin/kyuubi start
|
|
```
|
|
|
|
In the IDE, you set the corresponding parameters(host&port) in debug configurations, for example,
|
|
<div align=center>
|
|
|
|
|
|
|
|
</div>
|
|
|
|
## Debugging Apps
|
|
|
|
- Spark Driver
|
|
|
|
```bash
|
|
spark.driver.extraJavaOptions -agentlib:jdwp=transport=dt_socket,server=y,suspend=y,address=5005
|
|
```
|
|
|
|
- Spark Executor
|
|
```bash
|
|
spark.executor.extraJavaOptions -agentlib:jdwp=transport=dt_socket,server=y,suspend=y,address=5005
|
|
``` |
