## What changes were proposed in this pull request? Avoid memory problems in closure cleaning when handling large Gramians (>= 16K rows/cols) by using null as zeroValue ## How was this patch tested? Existing tests. Note that it's hard to test the case that triggers this issue as it would require a large amount of memory and run a while. I confirmed locally that a 16K x 16K Gramian failed with tons of driver memory before, and didn't fail upfront after this change. Closes #23600 from srowen/SPARK-26228.
