apache-spark - Spark 上下文 : Error initializing SparkContext While Running Spark Job

Question

我正在执行一个将数据从 Elastic Search 加载到 HDFS 的 Spark 程序，但我在初始化 SparkContext 时遇到错误。运行作业时出错。错误是在制作 spark session 期间。

Hadoop:3.2.1

Spark :2.4.4

Elasticsearch Spark(适用于 Spark 2.X)» 7.5.1

电子病历:6.0.0

代码:

from pyspark.sql import SparkSession
from pyspark.sql.functions import col, to_date

spark = SparkSession \
   .builder \
   .getOrCreate()

错误日志:

有人可以帮忙吗？谢谢。

Answer 1

这是因为您的 Spark 应用程序中缺少 Spark-Yarn JAR。如果您使用 Maven，请在您的 pom.xml 中添加以下内容。

1. 在依赖项下:

   <dependency>
     <groupId>org.apache.spark</groupId>
     <artifactId>spark-yarn_2.11</artifactId>
     <version>2.4.7</version>
   </dependency>

1. 在 artifactItems 下:

   <artifactItem>
     <groupId>org.apache.spark</groupId>
     <artifactId>spark-yarn_2.11</artifactId>
     <version>2.4.7</version>
     <type>jar</type>
     <overWrite>false</overWrite>
<outputDirectory>${project.build.directory}/classes/</outputDirectory>
     <destFileName>optional-new-name.jar</destFileName>
   </artifactItem>

注意:相应地更改您的 Scala 和 Spark 版本，因为我在这里使用的是 Spark 2.4.7 和 Scala 2.11。
