Gobblin Map-reduce作業在EMR上成功運行，但s3中沒有輸出

我正在運行gobblin，使用3節點EMR集羣將數據從kafka移動到s3。我在hadoop 2.6.0上運行，並且我還針對2.6.0構建了gobblin。Gobblin Map-reduce作業在EMR上成功運行，但s3中沒有輸出

看起來好像map-reduce作業成功運行。在我的hdfs我看到指標和工作目錄。指標有一些文件，但工作目錄爲空。 S3存儲桶應該有最終的輸出，但沒有數據。並在最後它說

輸出任務狀態路徑/ gooblinOutput /工作/ GobblinKafkaQuickStart_mapR3 /輸出/ job_GobblinKafkaQuickStart_mapR3_1460132596498不存在刪除工作目錄/ gooblinOutput /工作/ GobblinKafkaQuickStart_mapR3

這裏是最後的日誌：

不知道怎麼回事。有人可以幫忙嗎？

有2個問題

我data.publisher.final.dir = $ {ENV：GOBBLIN_WORK_DIR} /作業輸出

它應該是類似S3A：//dev.com/ gobblin-mapr6/

然後我以某種方式將特殊字符添加到topic.whitelist。所以，它無法識別主題
