我使用的命令是:
./elastic-mapreduce --jobflow j-12345678 --jar /home/hadoop/lib/emr-s3distcp-1.0.jar --args '--src,s3n://my-bucket/data/,--dest,hdfs:///data/in,--srcPattern,xyz01-1-1*ped*' --step-name "Copy input files to HDFS" --wait-for-steps
我試圖運行該取樣字計數的工作,以檢查是否存在與HDFS的任何問題,但它運行良好。
任何人都可以幫助我嗎?如果需要更多信息,請告訴我,我會更新說明。
您確定您的參數與您的命令示例類似嗎?該錯誤表示它試圖從HDFS讀取數據。 – SNeumann
是的,我所顯示的命令是我正在運行的實際命令。但從錯誤,我認爲它正在嘗試做一些中間操作(因爲它是從/ tmp目錄中刪除的東西) – Bhushan
