目录扩展在独立部署模式下不起作用:Apache Spark

Directory expansion does not work in standalone deployment mode : Apache Spark

我正在尝试使用以下命令在独立的 spark 集群上部署一个使用 spark streaming 的 Kafka 主题作业:

./bin/spark-submit --class MaxwellCdc.MaxwellSreaming
~/cdc/cdc_2.11-0.1.jar --jars ~/cdc/kafka_2.11-0.10.0.1.jar,
~/cdc/kafka-clients-0.10.0.1.jar,~/cdc/mysql-connector-java-5.1.12.jar,
~/cdc/spark-streaming-kafka-0-10_2.11-2.2.1.jar 

并得到这个异常:

如有任何帮助,我们将不胜感激。

引用文档:

When using spark-submit, the application jar along with any jars included with the --jars option will be automatically transferred to the cluster. URLs supplied after --jars must be separated by commas. That list is included in the driver and executor classpaths. Directory expansion does not work with --jars..

什么是目录扩展?

扩展文件名是指将相对文件名转换为绝对文件名。由于这是相对于默认目录完成的,因此您必须指定默认目录名以及要展开的文件名。 它还涉及扩展缩写,如 ~/

因此,请尝试为使用 --jars 选项提供的所有 jar 提供绝对路径。希望对您有所帮助。
