Yifei Yang updated ARROW-17783:
-------------------------------
Description:
When using arrow's aggregate kernel with table transferred from arrow flight
(DoGet), it may crash at arrow::util::CheckAlignment(). However using original
data it works well, also if I first serialize the transferred table into bytes
then recreate an arrow table using the bytes, it works well.
"flight-alignment-test" attached is the minimal test that can produce the
issue, which basically does "sum(total_revenue) group by l_suppkey" using the
table from "DoGet()". ("DummyNode" is just used to be the producer of the
aggregate node as the producer is required to create the aggregate node)

I'm still trying to reproduce the crash stably in a minimal test case...
