Question

我在本地计算机上启动并运行了Spark Master和Spark Slave。我想通过这样的命令行配置将我的代码提交给我运行的Spark Master，就像文档中所描述的那样https://spark.apache.org/docs/latest/configuration.html#dynamically-loading-spark-properties

JavaSparkContext sc = new JavaSparkContext(new SparkConf());
JavaStreamingContext jssc = new JavaStreamingContext(sc, BATCH_SIZE);
...

在构建我的.jar之后，我通过

提交

bin/spark-submit --class logAnalysis.myApp --name "myApp" --master "spark://some.server:7077" /jars/myApp-0.3.jar

编辑：我之前尝试过没有引号的主人。

在此之后，我得到以下错误：

17/03/22 12:23:02 WARN NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable

My Spark Master在作业列表中显示作业失败，因此我成功连接到我的主人。

当我通过

提交工作时

bin/spark-submit --class logAnalysis.myApp--name "myApp" --master local[8] /jars/myApp-0.3.jar

它运作得很好。

使用spark 2.0.2，我的scala版本不是问题所在，如本主题所述：Why is "Cannot call methods on a stopped SparkContext" thrown when connecting to Spark Standalone from Java application?

一切都有点默认设置。一些建议为什么会发生这种情况？

Answer 1

我现在已经在我的群集中添加了另一个节点。它已成功运行1x Master - 2x Worker Setup。

除了将ElasticSearch-HadoopConnector添加到配置之外，没有更改代码中的任何内容：

JavaSparkContext sc = new JavaSparkContext(new SparkConf().set("es.nodes", "node1").set("es.port", "9200"));

我不知道问题是什么，也许是由Config引起的。但如前所述，当将Master设置为local [*]时，作业成功运行。

（没有活动的SparkContext。）将Job提交给本地Spark master时出错
