java - Spark 独立模式下工作节点上的线程“主”java.lang.reflect.UndeclaredThrowableException 中的异常
问题描述
尝试使用 spark-submit 提交 spark 作业时出现以下错误。我无法理解错误到底是什么要求。
它在下线失败。
spark.read.format("com.mongodb.spark.sql.DefaultSource").
option("spark.mongodb.input.partitioner", "MongoSinglePartitioner").
option("uri", connectionString).
load()
这是我的火花提交命令：
spark-submit \
--class com.sparkTutorial.input \
--deploy-mode cluster \
--master "spark://master-node:7077" \
--packages com.microsoft.sqlserver:mssql-jdbc:7.4.1.jre11 \
--packages org.mongodb.spark:mongo-spark-connector_2.12:3.0.1 \
target/scala-2.12/sql-mongo-validation-assembly-0.1.jar
在工作节点上登录。
