私はsparkとscalaの新人です.YARNクライアントとしてSparkの仕事を提出するのは苦労しています。 (火花提出)スパークシェル経由でこれを行うと、同じ問題ありませんのために行く:eclipseからscalaを使用した糸クライアントへのsparkジョブの送信
しかしEclipseを使用してspark-submit --class ebicus.WordCount /u01/stage/mvn_test-0.0.1.jar
:最初のように、瓶にそれをコンパイルし、火花がカーネルシェル経由で提出する使用、その後日食にスパークジョブを作成します直接コンパイルしてYARNに提出するのは難しいようです。
プロジェクトの設定は次のとおりです。クラスタでCDH cloudera 5.6が実行されています。私は次のようにMy classpath/which is in sinc with my pom.xml
私のコードは、スカラ座を使用して、Mavenプロジェクトを持っている:

val sc = new SparkContext(conf);
val file = sc.textFile("hdfs://namecluster.com:8020/user/root/testdir/test.csv")
