Gobblin：java.lang.ClassNotFoundException：org.apache.gobblin.source.extractor.extract.jdbc.MysqlSource

Question

我正在尝试使用gobblin将mysql转换为hdfs数据。使用以下步骤运行mysql-to-gobblin.pull时：

1）启动hadoop：sbin\start-all.cmd

2）启动mysql服务：sudo service mysql start

3）设置GOBBLIN_WORK_DIR：export GOBBLIN_WORK_DIR=/mnt/c/users/name/incubator-gobblin/GOBBLIN_WORK_DIR

4）设置GOBBLIN_JOB_CONFIG_DIRexport GOBBLIN_JOB_CONFIG_DIR=/mnt/c/users/name/incubator-gobblin/GOBBLIN_JOB_CONFIG_DIR

5）独立启动bin/gobblin.sh service standalone start --jars /mnt/C/Users/name/incubator-gobblin/build/gobblin-sql/libs/gobblin-sql-0.15.0.jar

给出以下错误
