我正在尝试使用 gobblin 对 mysql 进行 hdfs 数据摄取。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_DIR
export 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

我正在从/mnt/c/users/name/incubator-gobblin/build/gobblin-distribution/distributions/gobblin-dist目录运行此命令。
我需要在这里做哪些改变？我该如何解决？
