Mahout 0.11.1 Spark-Shell NoClassDefFoundError

I am trying to get the Mahout Spark-Shell to run on the Cloudera QuickStart VM

Mahout: Version 0.11.1

Spark: Version 1.5.0-cdh5.5.1

Java: 1.7.0_67

.bashrc is set as

export MAHOUT_HOME=/home/cloudera/Desktop/Mahout_0_11_1
export MAHOUT_LOCAL=true
export SPARK_HOME=/usr/lib/spark
export JAVA_HOME=/usr/java/jdk1.7.0_67-cloudera

When I run the Mahout Spark-Shell I get the following error message.

java.lang.NoClassDefFoundError: com/sun/jersey/spi/container/servlet/ServletContainer

    at org.apache.mahout.sparkbindings.shell.MahoutSparkILoop.createSparkContext(MahoutSparkILoop.scala:89)
...

This is then followed by:

Mahout distributed context is available as "implicit val sdc".

Solution

in spark-env.sh,

add

export SPARK_DIST_CLASSPATH=$(/path/to/hadoop/bin/hadoop classpath)

and make sure that jersey-servlet-1.9.jar is on the classpath.

go through all of your *-env.sh scripts and be as explicit as possible about setting the environment variables, checking each, and then checking the logs for errors.

cd / find . -name jersey-servlet-1.9.jar and make sure the path where this file is found is on your classpath

Edit: Add jersey-server-1.9.jar to $MAHOUT_HOME/lib/ directory.
