Don't you need to preserve the task objects? Your implementation overwrites
each by the successor, so only the last task would be kept, despite your
print statements. Try building a list or dict of tasks like:
tasks =[] #only at the top
for file in glob('dags/snowsql/create/udf/*.sql'):
print("FILE {}".format(file))
tasks.append(
create_snowflake_operator(file, dag, 'snowflake_default')
)
tasks[-1].set_upstream(start)
