Hello all, Actually, I realised about this problem when trying to use Mahout, trying to create vectors using the
$MAHOUT_HOME/bin/mahout seqdirectory in my case: $MAHOUT_HOME/bin/mahout seqdirectory -i /home/hadoop/programming/docs-test/ -o jojolete --charset ascii command. This was not producing any output and after trying a lot to find the reason, I thought it was because I had first to copy the files to hadoop. Then I issued dfs -copyFromLocal ../../programming/docs-test docs-test-maho and I realised it "copies" the files but to zero byte files and I even spotted the "jojolete" output from mahout command and this is zero sized as well $HADOOP_HOME/bin/hadoop dfs -ls Found 5 items drwxr-xr-x - hadoop supergroup 0 2011-04-27 11:52 /user/hadoop/docs-test-mah drwxr-xr-x - hadoop supergroup 0 2011-04-27 12:00 /user/hadoop/docs-test-maho drwxr-xr-x - hadoop supergroup 0 2011-04-27 13:30 /user/hadoop/gutenberg drwxr-xr-x - hadoop supergroup 0 2011-04-26 17:46 /user/hadoop/jojolete drwxr-xr-x - hadoop supergroup 0 2011-04-26 14:26 /user/hadoop/testing-output I don't know if I'm doing something wrong, the commands never return any failure message. Maybe some of you have had a similar experience. I hope you can help me Cheers Liliana -- Liliana Paola Mamani Sanchez
