Weston Pace closed ARROW-13254.
-------------------------------
Fix Version/s: 5.0.0
Resolution: Duplicate
I'm going to go ahead and close this as a duplicate of ARROW-12983. If you try it on 5.0.0 (the next version to have the fix for ARROW-12983) or the latest nightly and the issue is still there then feel free to reopen.
