> In Pyspark 3.2 kernel with Jupyter notebook, When no cell is running and I 
> hit interrupt kernel, it actually kills pyspark kernel, where it's supposed 
> to do NOTHING.|
> I defined one startup script and in that startup script, If I override 
> default interrupt signal handler to SIGIGN, it works.

> work by default
