@user5285420 - run the code below to get a good view of what's going on. You should be able to find the query easily by looking at the value in the "command" column. Can you confirm if the BCP command still shows as status="Running" when the query steps are all complete?
select top 50
(case when requests.status = 'Completed' then 100
when progress.total_steps = 0 then 0
else 100 * progress.completed_steps / progress.total_steps end) as progress_percent,
requests.status,
requests.request_id,
sessions.login_name,
requests.start_time,
requests.end_time,
requests.total_elapsed_time,
requests.command,
errors.details,
requests.session_id,
(case when requests.resource_class is NULL then 'N/A'
else requests.resource_class end) as resource_class,
(case when resource_waits.concurrency_slots_used is NULL then 'N/A'
else cast(resource_waits.concurrency_slots_used as varchar(10)) end) as concurrency_slots_used
from sys.dm_pdw_exec_requests AS requests
join sys.dm_pdw_exec_sessions AS sessions
on (requests.session_id = sessions.session_id)
left join sys.dm_pdw_errors AS errors
on (requests.error_id = errors.error_id)
left join sys.dm_pdw_resource_waits AS resource_waits
on (requests.resource_class = resource_waits.resource_class)
outer apply (
select count (steps.request_id) as total_steps,
sum (case when steps.status = 'Complete' then 1 else 0 end ) as completed_steps
from sys.dm_pdw_request_steps steps where steps.request_id = requests.request_id
) progress
where requests.start_time >= DATEADD(hour, -24, GETDATE())
ORDER BY requests.total_elapsed_time DESC, requests.start_time DESC
