Hello, I use following command to seq2sparse on Amazon.
*elastic-mapreduce --jar s3://XXX/mahout-examples-0.8-SNAPSHOT-job.jar --main-class org.apache.mahout.driver.MahoutDriver --arg seq2sparse --arg --input --arg s3://XXX/data.seqdir --arg -o --arg s3://XXX/data.vectors --arg --weight --arg tfidf --arg --maxDFPercent --arg 80 --arg --maxNGramSize --arg 3 --arg --overwrite --arg --namedVector --arg --logNormalize --arg --numReducers --arg 1 -j JOB_ID* But the job never completes and i have the following error. Any suggestion to solve this issue? *attempt_201209101934_0008_r_000000_1: SLF4J: Class path contains multiple SLF4J bindings.* *attempt_201209101934_0008_r_000000_1: SLF4J: Found binding in [jar:file:/home/hadoop/lib/slf4j-log4j12-1.6.1.jar!/org/slf4j/impl/StaticLoggerBinder.class] * *attempt_201209101934_0008_r_000000_1: SLF4J: Found binding in [jar:file:/mnt3/var/lib/hadoop/mapred/taskTracker/hadoop/jobcache/job_201209101934_0008/jars/job.jar!/org/slf4j/impl/StaticLoggerBinder.class] * *attempt_201209101934_0008_r_000000_1: SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.* *java.lang.IllegalStateException: /data.vectors/dictionary.file-0* * at org.apache.mahout.common.iterator.sequencefile.SequenceFileIterable.iterator(SequenceFileIterable.java:63) * * at org.apache.mahout.vectorizer.term.TFPartialVectorReducer.setup(TFPartialVectorReducer.java:130) * * at org.apache.hadoop.mapreduce.Reducer.run(Reducer.java:174)* * at org.apache.hadoop.mapred.ReduceTask.runNewReducer(ReduceTask.java:663)* * at org.apache.hadoop.mapred.ReduceTask.run(ReduceTask.java:426)* * at org.apache.hadoop.mapred.Child$4.run(Child.java:255)* * at java.security.AccessController.doPrivileged(Native Method)* * at javax.security.auth.Subject.doAs(Subject.java:396)* * at org.apache.hadoop.security.UserGroupInformation.doAs(UserGroupInformation.java:1132) * * at org.apache.hadoop.mapred.Child.main(Child.java:249)* *Caused by: java.io.FileNotFoundException: File does not exist: hdfs:// 10.140.5.86:9000/data.vectors/dictionary.file-0* * at org.apache.hadoop.hdfs.DistributedFileSystem.getFileStatus(DistributedFileSystem.java:517) * * at org.apache.hadoop.fs.FileSystem.getLength(FileSystem.java:798)* * at org.apache.hadoop.io.SequenceFile$Reader.<init>(SequenceFile.java:1538)* * at org.apache.hadoop.io.SequenceFile$Reader.<init>(SequenceFile.java:1533)* * at org.apache.mahout.common.iterator.sequencefile.SequenceFileIterator.<init>(SequenceFileIterator.java:58) * * at org.apache.mahout.common.iterator.sequencefile.SequenceFileIterable.iterator(SequenceFileIterable.java:61) * * ... 9 more* * * *attempt_201209101934_0008_r_000000_2: SLF4J: Class path contains multiple SLF4J bindings.* *attempt_201209101934_0008_r_000000_2: SLF4J: Found binding in [jar:file:/home/hadoop/lib/slf4j-log4j12-1.6.1.jar!/org/slf4j/impl/StaticLoggerBinder.class] * *attempt_201209101934_0008_r_000000_2: SLF4J: Found binding in [jar:file:/mnt3/var/lib/hadoop/mapred/taskTracker/hadoop/jobcache/job_201209101934_0008/jars/job.jar!/org/slf4j/impl/StaticLoggerBinder.class] * *attempt_201209101934_0008_r_000000_2: SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.* *Exception in thread "main" java.lang.IllegalStateException: Job failed!* * at org.apache.mahout.vectorizer.DictionaryVectorizer.makePartialVectors(DictionaryVectorizer.java:321) * * at org.apache.mahout.vectorizer.DictionaryVectorizer.createTermFrequencyVectors(DictionaryVectorizer.java:191) * * at org.apache.mahout.vectorizer.SparseVectorsFromSequenceFiles.run(SparseVectorsFromSequenceFiles.java:272) * * at org.apache.hadoop.util.ToolRunner.run(ToolRunner.java:65)* * at org.apache.hadoop.util.ToolRunner.run(ToolRunner.java:79)* * at org.apache.mahout.vectorizer.SparseVectorsFromSequenceFiles.main(SparseVectorsFromSequenceFiles.java:55) * * at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)* * at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) * * at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) * * at java.lang.reflect.Method.invoke(Method.java:597)* * at org.apache.hadoop.util.ProgramDriver$ProgramDescription.invoke(ProgramDriver.java:68) * * at org.apache.hadoop.util.ProgramDriver.driver(ProgramDriver.java:139)* * at org.apache.mahout.driver.MahoutDriver.main(MahoutDriver.java:195)* * at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)* * at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) * * at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) * * at java.lang.reflect.Method.invoke(Method.java:597)* * at org.apache.hadoop.util.RunJar.main(RunJar.java:187)* -- Necati DEMİR --------------------
