Hello,

I have the issue that even a query like "select 1" is not finishing. The sql warehouse runs infinite. I have no idea where to look for any issues because in the SPARK UI I cant see any error.

What is intresting is that also allpurpose clusters (multi node) are also affected

%sql
select 1

wont finish.

If I choose a single node cluster the thing is finishing within 2 seconds. 

Any help would be appreciated that leads to the solution
