reads success with spark job but not with cqlsh query when huge tombstones present


i have a table with huge tombstones.So when i performed a spark job (which reads) on that specific table , it gave result without any issues.But i executed same query using cqlsh it gave me error because huge tombstones present in that table.
("Cassandra failure during read query at consistency one(1 replica needed but o replicas responded ,1 failed).
i know tombstones should not be there, i can run repair to avoid them , but apart from that why spark succeeded and cqlsh failed.they both use same sessions and queries.
How spark-cassandra connector works? is it different than cqlsh?
Please let me know .
thank you
