AWS EMR, zeppelin

Bootstrapping Zeppelin EMR

Omid

a few notes before we lunch an emr cluster with zeppelin:

  • Zeppelin is installed on the master node of the EMR cluster ( choose the right installation for you )

If you want, you can automate the above process by using an EMR step. Please find attached a simple shell script that will download your zeppelin-site.xml file from S3 onto your EMR cluster and restart the Zeppelin service.

To run it, simply copy the script to an S3 bucket and then use the script-runner.jar process as outlined in [2] below with the script s3 location as its only argument.

To do this via the AWS EMR Console:

1  – Under the “Add steps (optional)” section, select “Custom JAR” for the “Step type” and click the “Configure” button.

2 – In the pop-up window, for us-east-1 the JAR location for script-runner.jar is:

s3://us-east-1.elasticmapreduce/libs/script-runner/script-runner.jar

3 – For the argument, you would pass in your S3 bucket and location of the “setupZeppelin.sh” file e.g.,:

s3://mybucket/mylocation/setupZeppelin.sh

Once done, click “Add” and continue on with your EMR cluster creation (this process is included when cloning an EMR cluster).

Zeppelin Config optimisation

  • In the interpreter
    • zeppelin.interpreter.output.limit 1024 instead 102400
    • zeppelin.spark.maxResult 100 instead of 1000
  • In zeppelin-env.sh
    sudo nano /etc/zeppelin/conf.dist/zeppelin-env.sh

    • export ZEPPELIN_MEM=”-Xms44024m -Xmx46024m -XX:MaxPermSize=512m”
    • export ZEPPELIN_INTP_MEM=”-Xms44024m -Xmx46024m -XX:MaxPermSize=512m”
