Amazon Elastic MapReduce: FileSystem Exception

I run my app using ruby ​​client: ruby ​​elastic-mapreduce -j j-20PEKMT9BRSUC --jar s3n: //sakae55/lib/edu.cit.som.jar --main-class edu.cit.som.hadoop .SOMDriver --arg s3n: // sakae55 / repository / input / ecoli / -arg s3n: // sakae55 / repository / output / ecoli / pl / -arg s3n: //sakae55/repository/data/ecoli/som.txt

Then I see the following error:

java.lang.IllegalArgumentException: This filesystem object (file: ///) does not support access to the request path "hdfs: // i -10-195-207-230.ec2.internal: 9000 / mnt / var / lib / hadoop / tmp / mapred / system / job_201004221221_0017 / job.jar 'You may have called Fi eSystem.get (conf) when you have to call FileSystem.get (uri, conf) to get the filesystem supporting your path. to org .apache.hadoop.fs.FileSystem.checkPath (FileSystem.java:320) at org.apache.hadoop.fs.RawLocalFileSystem.pathToFile (RawLocalFileSystem.java:52) at org.apache.hadoop.fs.RawLocalFileSystem.getFileStile .java: 416) at org.apache.hadoop.fs.FilterFileSystem.getFileStatus (FilterFileSystem.java:259) at org.apache.hadoop.fs.FileSystem.isDirectory (FileSystem.java:676) at org.apache.hadoop. fs.FileUtil.copy (FileUtil.java:200) at org.apache.hadoop.fs.FileSystem.copyFromLocalFile (FileSystem.java:1184) at org.apache.hadoop.fs.FileSystem.copyFromLocalFile (FileSystem.java:1160) at org.apache.hadoop.fs.FileSystem .copyFromLocalFile (FileSystem.java:1132) at org.apache.hadoop.mapred.JobClient.configureCommandLineOptions (JobClient.java:662) at org.apache.hadoop.mapred.JobClient.submitJob (JobClient.java:729 apache.hadoop.mapred.JobClient.runJob (JobClient.java:1026) at edu.cit.som.hadoop.SOMDriver.runIteration (SOMDriver.java:106) at edu.cit.som.hadoop.SOMDriver.train (SOMDriver. java: 69) at edu.cit.som.hadoop.SOMDriver.run (SOMDriver.java:52) at org.apache.hadoop.util.ToolRunner.run (ToolRunner.java:65) at org.apache.hadoop.util .ToolRunner.run (ToolRunner.java:79) at edu.cit.som.hadoop.SOMDriver.main (SOMDriver.java:36) at sun.reflect.NativeMethodAccessorImpl.invoke0 (native method) at sun.reflect.NativeMethodAccessorImpl.invoke (NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke at java.lang.reflect.Method.invoke (Method.java:597) at org.apache.hadoop.util.RunJar.main (RunJar.java:155) at org.apache.hadoop.mapred.JobShell.run (JobShell .java: 54) to org.apache.hadoop.util.ToolRunner.run (ToolRunner.java:65) to org.apache.hadoop.util.ToolRunner.run (ToolRunner.java:79) to org.apache.hadoop. mapred.JobShell.main (JobShell.java:68)reflect.DelegatingMethodAccessorImpl.invoke (DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke (Method.java:597) at org.apache.hadoop.util.RunJar.main (RunJar.java:155) at org .apache.hadoop.mapred.JobShell.run (JobShell.java:54) at org.apache.hadoop.util.ToolRunner.run (ToolRunner.java:65) at org.apache.hadoop.util.ToolRunner.run (ToolRunner .java: 79) to org.apache.hadoop.mapred.JobShell.main (JobShell.java:68)reflect.DelegatingMethodAccessorImpl.invoke (DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke (Method.java:597) at org.apache.hadoop.util.RunJar.main (RunJar.java:155) at org .apache.hadoop.mapred.JobShell.run (JobShell.java:54) at org.apache.hadoop.util.ToolRunner.run (ToolRunner.java:65) at org.apache.hadoop.util.ToolRunner.run (ToolRunner .java: 79) to org.apache.hadoop.mapred.JobShell.main (JobShell.java:68)79) at org.apache.hadoop.mapred.JobShell.main (JobShell.java:68)79) at org.apache.hadoop.mapred.JobShell.main (JobShell.java:68)

I'm not sure why the error is referring to "file: ///" even though all the arguments I pass are not using the schema.
