Flink Кассандра Раковина держит время?

Я запускаю приложение Flink с приемником Cassandra и параллелизмом 10, и всегда происходит нечто подобное: 

Caused by: java.lang.Exception: Cannot deploy task Sink: Cassandra Sink (7/10) (36a9412d74cfb37f29448dcd699e44a5) - TaskManager (833bea2172578b0bffdc7075eb992874 @ localhost (dataPort=-1)) not responding after a timeout of 10000 ms

По каким причинам это может происходить?Это связано с параллелизмом и если да, то есть ли способ это исправить?
