Gobblin在纱线上的运行任务失败，因为“无法找到或加载主类org.apache.gobblin.yarn.GobblinYarnTaskRunner”

Question

我正在尝试在纱上部署gobblin，并成功将GobblinYarn作业提交到我的集群。但是无法运行gobblin任务，堆栈跟踪如下：

2019-02-25 13:34:11 CST INFO  [AMRM Callback Handler Thread] org.apache.gobblin.yarn.YarnService  - Received the following diagnostics information for container container_e03_1549849284613_0015_01_000005: Exception from container-launch.
Container id: container_e03_1549849284613_0015_01_000005
Exit code: 1

Container exited with a non-zero exit code 1. Error file: prelaunch.err.
Last 4096 bytes of prelaunch.err :
Last 4096 bytes of GobblinYarnTaskRunner.stderr :
Error: Could not find or load main class org.apache.gobblin.yarn.GobblinYarnTaskRunner

我的环境很好，因为我的纱簇接受了地精工作。

我还检查了负责启动的容器，“ gobblin-yarn.jar”在文件缓存中。

我感到困惑的是什么地方出了问题，我该如何解决？任何建议都值得赞赏。
