I figured it out, I tunnel to 4040 and 8080 but missed the one for 8081. After adding 8081 port, it worked.

Thanks, Anders. It's very helpful for me to setup the apache zeppelin on AWS EMR cluster. And I just add installing nodejs, npm into your script.

sudo yum -y install nodejs npm --enablerepo=epel

Hi Anders!

I launched EMR cluster with same version of software as I can see here,
Applied your file (manually),

When I enter Zeppelin and try to actually do something in Scala in a notebook I get this. Ever bumped into this?

people.take(10)

I think that you can add the below one in the common.sh

+ addJarInDir "${SPARK_HOME}/classpath/emr"
+ addJarInDir "${SPARK_HOME}/classpath/emrfs"
+ addJarInDir "${HADOOP_HOME}/share/hadoop/common/lib"
+ addJarInDir "${HADOOP_HOME}/share/hadoop/common/lib/hadoop-lzo.jar"

Thanks for you all comments. I recently updated the script so that it works with Amazon EMR release 4.x clusters.

Note that the script is still using Zeppelin's bundled Spark installation since I haven't been able to get Zeppelin to work together with Amazon's Spark installation (via SPARK_HOME/HADOOP_HOME) yet.

Doesn't look like good idea to patch master in this way: Zeppelin updates this file and patch doesn't work...

anyway, i stuck with "org.apache.spark.SparkException: Found both spark.driver.extraClassPath and
SPARK_CLASSPATH. Use only the former."

@mwacc,
I've got same problem and fixed it with changing ./bin/interpreter.sh
CLASSPATH+=":${ZEPPELIN_CLASSPATH}"

SparkException: Found both spark.driver.extraClassPath and SPARK_CLASSPATH. Use only the former

export SPARK_CLASSPATH+=":${CLASSPATH}"
if [[ -n "${SPARK_SUBMIT}" ]]; then
${SPARK_SUBMIT} --class ${ZEPPELIN_SERVER} --driver-java-options "${JAVA_INTP_OPTS}" ${SPARK_SUBMIT_OPTIONS} ${SPARK_APP_JAR} ${PORT} &
else
${ZEPPELIN_RUNNER} ${JAVA_INTP_OPTS} -cp ${CLASSPATH} ${ZEPPELIN_SERVER} ${PORT} &

Hello guys

I followed the instructions here got the zeppelin working on AWS EMR cluster with spark for release label 4.4.0.

But now I faced an issue when I try to add R interpreter in zeppelin. The maven command I used is

mvn clean package -Pyarn -Pr -DskipTests

I am trying to use the spark provided by EMR cluster so in zeppelin-env.sh I had this configuration:
export MASTER=yarn-client
export HADOOP_HOME=/usr/lib/hadoop
export SPARK_HOME=/usr/lib/spark
export HADOOP_CONF_DIR=/etc/hadoop/conf
export ZEPPELIN_SPARK_USEHIVECONTEXT=false
export ZEPPELIN_JAVA_OPTS="${ZEPPELIN_JAVA_OPTS[@]}"
export PYTHONPATH=$PYTHONPATH:/usr/lib/spark/python

Added spark_home variable

But now it doesn't work even for the spark interpreter.

There is another small issue I want to ask here, when I change something in zeppelin-env.sh and save the file then restart zeppelin-deamon, I should expect the change got applied immediately right? Or do I need to do something else to make sure the change applied? Right now I don't see the change made in zeppelin-env.sh get applied after I restarted zeppelin.

Thanks in advance

Hello guys, can this be run on an existing EMR cluster?

Hi I am using Zeppelin on the new EMR as it's now a built in option. I notice there's no %dep interpreter. How are we to add external packages?

anyone got it working on EMR 5.8.0 ?

since there were no answers, I've created a simple bootstrap script to install Zeppelin 0.8 on EMR (tested with EMR 5.16.0)
