mahout 0.5 multiple SLF4J bindings
hi,guys
I am a beginner. I download mahout 0.5 src and build it with mvn
-DskipTests install.
when I excute
"bin/mahout org.apache.mahout.clustering.syntheticcontrol.kmeans.Job" then
system return following,
but when I use
"hadoop jar /usr/mahout-distribution-0.5/examples/target/mahout-examples-0.5-job.jar
org.apache.mahout.clustering.syntheticcontrol.canopy.Job
", it works and program start running. when I use "bin/mahout vectordump
--seqFile /user/hadoopuser/output/data/part-00000" command to check the
output,
the multiple SLF4J bindings problem comes again.
Can Somebody give me some help. Thans a lot.

Re: mahout 0.5 multiple SLF4J bindings

You do not need a separate Hadoop cluster. Mahout has Hadoop built in.
This runs Hadoop in "pseudo-distributed" mode, inside one computer.
Use the $MAHOUT_HOME/bin/mahout program to run Mahout programs.

Thank you. There are too many version of hadoop and mahout. I am a little
bit confused which version mahout should run on which version hadoop. I
will try mahout 0.6.

As you can see from the log, the problem has nothing to do with slf4j.
That's just a trivial warning. The problem is you're using an incompatible
version of Hadoop.

0.6 has been released. Is there a reason that you don't use that?
