Debugging Kyuubi

You can use the Java Debug Wire Protocol 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,

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,

Debugging Apps

  • Spark Driver
spark.driver.extraJavaOptions   -agentlib:jdwp=transport=dt_socket,server=y,suspend=y,address=5005
  • Spark Executor
spark.executor.extraJavaOptions   -agentlib:jdwp=transport=dt_socket,server=y,suspend=y,address=5005
