I’m moving from 2.5 to 3.1 – I see the following error in one of my queries:
The global accumulator "@@null" has not been declared
The error indicate an empty line. There is no accumulator named @@null anywhere in the query?
I also get:
(2, 2) Error: The feature is not supported yet in batch mode query.
For a static accumulator. My understanding is that “batch mode” means “distributed,” but this is a single node installation.
Any idea what’s going on?
