Hi, I am not sure if this question has been asked. Its more of a hadoop fs question. I am trying to execute the following hadoop fs command :
hadoop fs -copyToLocal s3n://<Access Key>:<Secret Key>@<bucket name>/file.txt /home/hadoop/workspace/file.txt When I execute this command directly from the Terminal shell, it works perfectly fine, however the above command from code doesn't execute. In fact, it says : Exception in thread "main" copyToLocal: null Please note I am using Runtime.getRunTime().exec(cmdStr), where cmdStr is the above hadoop command. Also, please note that hadoop fs -cp or hadoop fs -rmr commands work fine with source and destination being both Amazon AWS locations. In the above command (hadoop fs -copyToLocal) the destination is local location to my m/c. Your help would be greatly appreciated. Thanks, Neeral
