我正在运行gobblin，使用3节点emr集群将数据从kafka移动到s3。我运行的是hadoop2.6.0，我还针对2.6.0构建了gobblin。
似乎map reduce作业运行成功。在我的hdfs上，我看到了度量和工作目录。metrics有一些文件，但工作目录为空。s3 bucket应该有最终输出，但没有数据。最后它说
输出任务状态路径/gooblinoutput/working/gobblinkafkaquickstart\u mapr3/output/job\u gobblinkafkaquickstart\u mapr3\u 1460132596498不存在已删除的工作目录/gooblinoutput/working/gobblinkafkaquickstart\u mapr3
以下是最终日志：
