Hi
I hope you are well.
While following this tutorial
https://mahout.apache.org/users/sparkbindings/play-with-shell.html
I ran into some problems.
At point 4. of "Starting Mahout's Spark shell", executing `bin/mahout
spark-shell` returns
Error: Could not find or load main class
org.apache.mahout.sparkbindings.shell.Main
so I had a look at classes folder's tree and ./bin/mahout's source code.
vagrant@vagrant-ubuntu-trusty-64:~/tl/mahout$ ls -l
$MAHOUT_HOME/spark-shell/target/
total 40

while line 180 in ./bin/mahout reads
for f in $MAHOUT_HOME/spark-shell/target/mahout-spark-shell-*.jar ; do
Now, by applying the following diff
diff --git a/bin/mahout b/bin/mahout
index 5f54181..a6f4ba8 100755
--- a/bin/mahout
+++ b/bin/mahout

+ for f in $MAHOUT_HOME/spark-shell/target/mahout-spark-shell_*.jar ; do

done
I'm now able to get to mahout's shell after running `./bin/mahout
spark-shell`, but I get the following errors
Using Scala version 2.10.3 (OpenJDK 64-Bit Server VM, Java 1.7.0_55)

Has anyone any idea of what's going on/wrong? Any hints on what I'm doing
wrong or how I could fix this?
Thanks in advance, and thanks for the awesome project.
Looking forward to participate.
