I am trying to run Kmeans with cosine similarity measure on mahout with hadoop to cluster text documents. I was able to cluster the documents, however, when I tried to view the output of the clusters with clusterdump I received the following error:
Exception in thread "main" java.io.IOException: Unable to create parent directories of /mydocs/mytext-out-clust0
Could it be a permission problem? Please any clue on this will be appreciated. Thanks.
Hello,
It seems that the directory cannot be created due to incorrect permissions. Try to fix the permissions for directory "/mydocs". You can either run the command as a sudoer or chmod 777 the directory.
Thanks,
Thanks @Costa. The issue is, it was in this same directory that I was able to write the clusters output, cluster centroids, tfidf vectors and lots of files. That is what really surprise me. How come it couldn't create that specific file. I have check the permission on that folder and I have already been able to write to it.
Hello,
The output file is written in the local filesystem, then the /mydocs/mytext-out-clust0 must exist in the local machine and the user should have write permissions.
@Christian you mean I should manually create that directory? Thanks for the suggestion. I will try that and see what I get.
@Adewole, yes, the /mydocs folder must exist in your local filesystem. Alternatively, you can change your output folder (e.g to your home: -o $HOME/mytext-out-clust0 )
