Big Data Tools Core doesn't work anymore
I was using Big Data Tools Core in PyCharm, and I see now that the plugin requires intellij.java.psi, which doesn't seem to be available in PyCharm. Given that Python is often used for Big Data processing, is this just a version mismatch between PyCharm and the plugin, or is Big Data Tools no longer available in PyCharm?

This is a known problem in 2026.2, tracked as IJPL-249064. The 2026.2 update accidentally gave the plugin a hard dependency on the
intellij.java.psimodule, which only exists in IDEs with Java support. That is why the plugin no longer loads in PyCharm, and the same thing happens in DataGrip, Rider, CLion, and the other non-Java IDEs.The fix is ready and has been verified on our side. It ships as a Big Data Tools plugin update, so you will not need to wait for a new PyCharm release. Once it reaches a public build, the exact version will appear in the "Available in" field on IJPL-249064. You can follow the issue to get notified when that happens, see https://intellij-support.jetbrains.com/hc/en-us/articles/207241135 for how.
Until then, the only workaround is to roll back to PyCharm 2026.1.x, where the plugin still loads. There is no way to fix it in place, since the missing module cannot be installed into PyCharm separately.
