Deneche A. Hakim commented on DRILL-1852:
-----------------------------------------
After further investigations it turned out the problem was coming from
optiq-drill r12. Basically, Optiq doesn't expect a '*' identifier when checking
for the monotonicity of columns and throws an assertion error. I created a
[pull request|https://github.com/amansinha100/optiq/pull/1] to fix the problem
in Optiq-drill and tested it locally to make sure this exception doesn't happen
anymore:
I will leave this issue open until the fix is merged into optiq-drill, then I
will add a test to make sure this exception doesn't happen again.
