如果我以「sbt run」運行，下面的簡單spark程序運行得非常好。但如果我跑，Spark Streaming throwing java.net.ConnectException
1）作爲「spark-submit.cmd eventfilter-assembly-0.1-SNAPSHOT.jar」。其中jar是使用「sbt assembly」與「streaming and sql」的sbt規則創建的「％provided」創建的。
2）作爲「spark-submit.cmd --jar play-json_2.10-2.3.10.jar seventfilter_2.10-0.1-SNAPSHOT.jar」。
這兩種情況下，它都會啓動並等待新文件的到來。直到現在沒有問題。
但是，只要我開始放置文件，以便它可以流式傳輸，下面的異常來了。
注：我使用的火花1.4.1彬hadoop2.6，
注：如果說我是「SBT運行」運行時，它運行平穩幾個小時。
注意：我也嘗試過1.5.2，通過相應地更改sbt文件。行爲是一樣的。
