Jason Altekruse commented on DRILL-1753:
----------------------------------------
I was incorrect when I said this issue was not related to 1673. Originally a
subset of the issue described 1673 was fixed. That issue was reopened and the
complete fix was applied. The query reported as failing here now passes on
master. I am closing it as fixed.
> Flatten fails on a repeated map, where the maps being flattened contain
> repeated lists
