If the query is returning empty result , without your shuffle service and
aqe turned on, then the issue could be
1) Bug in AQE
or
2) Wrong stats, resulting in empty relation optimization kicking in. so
check the stats..  run analyze table  command before querying,

If it happens only with your custom Shuffle service, then bug is likely in
your code..
