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) Review comment: Can we explicitly state that the remote debugger is available only PyCharm Professional (I know, it is clearly explained in PyCharm docs, but not everyone will get there)? And maybe link to [pydev remote debugger docs](https://www.pydev.org/manual_adv_remote_debugger.html) as an alternative. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
