运行spark-submit命令示例
bin/spark-submit \
--class org.apache.spark.examples.SparkPi \
--master yarn \
--deploy-mode cluster \
./examples/jars/spark-examples_2.12-3.0.0.jar \
1000
出现报错:Failed to get main class in JAR with error null . Please specify one with --class.主要是时说找不到程序入口
原因:最新的spark更改了示例,现在官方文档
./bin/spark-submit --class org.apache.spark.examples.SparkPi \
--master yarn \
--deploy-mode cluster \
--driver-memory 4g \
--executor-memory 2g \
--executor-cores 1 \
--queue thequeue \
examples/jars/spark-examples*.jar \
