Hi, I'm a newbie at both Mahout and Hadoop environments, so I started to run some predefined examples, such as cluster reuters. Everything went well until I've tried to visualize the results with clusterdump command. I've tried this:
mahout clusterdump -i /teste/reuters-kmeans/clusters-*-final -o /teste/clusterdump -d /teste/reuters-out-seqdir-sparse-kmeans/dictionary.file-0 -dt sequencefile -b 100 -n 20 --evaluate -dm org.apache.mahout.common.distance.CosineDistanceMeasure --pointsDir /teste/reuters-kmeans/clusteredPoints And, although I've changed the output directory to anything possible, I always get this error: Exception in thread "main" java.io.IOException: Unable to create parent directories of /teste/clusterdump at com.google.common.io.Files.createParentDirs(Files.java:645) at org.apache.mahout.utils.clustering.ClusterDumper.printClusters(ClusterDumper.java:186) (...) I dont think it has anything to do with hdfs permissions, since all the previous steps (seq2sparse, kmeans, etc) went well and created their desired directories. I would appreciate any help or tip. And sorry if I'm sending this email to the wrong mail-list. Thanks, Henrique
