Hello, I am practicing the NewsKMeansClustering.java, an example code given in chapter 9 of Mahout-in-Action? I run this program against a directory of sequence files. The output error message is as follows:
Exception in thread "main" java.io.FileNotFoundException:* File newsClusters/clustersclusteredPoints/part-m-00000 does not exist*. at org.apache.hadoop.fs.RawLocalFileSystem.getFileStatus(RawLocalFileSystem.java:361) at org.apache.hadoop.fs.FilterFileSystem.getFileStatus(FilterFileSystem.java:245) at org.apache.hadoop.fs.FileSystem.getLength(FileSystem.java:676) at org.apache.hadoop.io.SequenceFile$Reader.(SequenceFile.java:1417) at org.apache.hadoop.io.SequenceFile$Reader.(SequenceFile.java:1412) at mia.clustering.ch09.NewsKMeansClustering.main(NewsKMeansClustering.java:76) As reference, the directory structure of the result generated after running this program is shown as follows as well: ~/workspaceMahout1/recommender/newsClusters% ls canopy-centroids clusters df-count dictionary.file-0 frequency.file-0 tfidf-vectors tf-vectors tokenized-documents wordcount ~/workspaceMahout1/recommender/newsClusters/clusters/clusteredPoints% ls part-m-00000 Afterwards, I change the code from the original one new Path(clusterOutput+Cluster.CLUSTERED_POINTS_DIR +”/part-m-00000”), conf); to *new Path(clusterOutput+”/clusteredPoints”+”/part-m-00000”), conf);* The program can go through without giving the above error messages. I would like to know is that a bug in the original code or are there any other hidden issues?
