If a PySpark application does not require interaction +between Python workers and JVMs, Python workers are not launched. They are lazily launched only when +Python native functions or data have to be handled, for example, when you execute pandas UDFs or +PySpark RDD APIs. + +This page describes how to debug such Python applications and workers instead of focusing on debugging with JVM. +Profiling and debugging JVM is described at `Useful Developer Tools <https://spark.apache.org/developer-tools.html>`_. + + +Remote Debugging (PyCharm Professional) +--------------------------------------- + +In order to debug the Python workers remotely, you should connect from the Python worker to the debug server in PyCharm. +This section describes remote debugging within a single machine to demonstrate easily. +In order to debug PySpark applications on other machines, please refer to the full instructions that are specific +to PyCharm, documented `here <https://www.jetbrains.com/help/pycharm/remote-debugging-with-product.html>`_. + +Firstly, choose **Edit Configuration...** from the **Run** menu. It opens the Run/debug Configurations dialog. +You have to click ``+`` configuration on the toolbar, and from the list of available configurations, select **Python Debug Server**. +Enter the name of this run/debug configuration, for example, ``MyRemoteDebugger`` and also specify the port number, for example ``12345``.
