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:

不知道发生了什么。有人能帮忙吗?

有两个问题
我有data.publisher.final.dir=${env:gobblin_work_dir}/工作输出
它应该类似于s3a://dev.com/gobblin-mapr6/
然后我在topic.whitelist中添加了一些特殊的字符。因此,它无法识别主题
