Question

How to run Gobblin in debug mode from IntelliJ IDE using bin/gobblin-standalone.sh command?

Getting started tutorial suggests how to run sample Gobblin job, but it is unclear how to debug it.

Answer 1

You can start remote debugger in IntelliJ, and then configure Gobblin JVM to connect to it.

In IntelliJ, add a "Remote" debug configuration. Make sure to set the "Debugger mode" to Listen. Check "Auto restart" box, if it's available.

Set a breakpoint in your code

Start the "Remote" debug configuration:

Start Gobblin with extra command line option --jvmopts :

bin/gobblin service standalone start --jvmopts -agentlib:jdwp=transport=dt_socket,server=n,address=localhost:5005,suspend=n
