Architecture

Instructions

Step 1

Create S3 EMR bucket.

# change me
ZEPPELIN_DEMO_BUCKET="your-bucket-name"

aws s3api create-bucket \
    --bucket ${ZEPPELIN_DEMO_BUCKET}
aws s3api put-public-access-block \
    --bucket ${ZEPPELIN_DEMO_BUCKET} \
    --public-access-block-configuration \
    BlockPublicAcls=true,IgnorePublicAcls=true,BlockPublicPolicy=true,RestrictPublicBuckets=true

Copy EMR config files to S3.

aws s3 cp bootstrap/bootstrap.sh s3://${ZEPPELIN_DEMO_BUCKET}/bootstrap/
aws s3 cp bootstrap/helium.json s3://${ZEPPELIN_DEMO_BUCKET}/bootstrap/
aws s3 cp sql/ratings.sql s3://${ZEPPELIN_DEMO_BUCKET}/bootstrap/

Step 2

Create EMR Roles.

aws emr create-default-roles

Create S3 EMR log bucket.

# change me
LOG_BUCKET="aws-logs-your_aws_account_id-your_region"

aws s3api create-bucket --bucket ${LOG_BUCKET}
aws s3api put-public-access-block --bucket ${LOG_BUCKET} \
    --public-access-block-configuration \
    BlockPublicAcls=true,IgnorePublicAcls=true,BlockPublicPolicy=true,RestrictPublicBuckets=true

Step 3

Create single-node Amazon EMR cluster.

# change me
ZEPPELIN_DEMO_BUCKET="your-bucket-name"
EC2_KEY_NAME="your-key-name"
LOG_BUCKET="aws-logs-your_aws_account_id-your_region"
GITHUB_ACCOUNT="your-account-name"
GITHUB_REPO="your-new-project-name"
GITHUB_TOKEN="your-token-value"
MASTER_INSTANCE_TYPE="m5.xlarge" # optional

aws cloudformation create-stack \
    --stack-name zeppelin-emr-dev-stack \
    --template-body file://cloudformation/emr_single_node.yml \
    --parameters ParameterKey=ZeppelinDemoBucket,ParameterValue=${ZEPPELIN_DEMO_BUCKET} \
                 ParameterKey=Ec2KeyName,ParameterValue=${EC2_KEY_NAME} \
                 ParameterKey=LogBucket,ParameterValue=${LOG_BUCKET} \
                 ParameterKey=MasterInstanceType,ParameterValue=${MASTER_INSTANCE_TYPE} \
                 ParameterKey=GitHubAccount,ParameterValue=${GITHUB_ACCOUNT} \
                 ParameterKey=GitHubRepository,ParameterValue=${GITHUB_REPO} \
                 ParameterKey=GitHubToken,ParameterValue=${GITHUB_TOKEN}

Create Amazon RDS PostgreSQL database.

# change me
DB_MASTER_USER="your-db-username"
DB_MASTER_PASSWORD="your-db-password"
MASTER_INSTANCE_TYPE="db.m4.large" # optional

aws cloudformation create-stack \
    --stack-name zeppelin-rds-stack \
    --template-body file://cloudformation/rds_postgres.yml \
    --parameters ParameterKey=DBUser,ParameterValue=${DB_MASTER_USER} \
                 ParameterKey=DBPassword,ParameterValue=${DB_MASTER_PASSWORD} \
                 ParameterKey=DBInstanceClass,ParameterValue=${MASTER_INSTANCE_TYPE}

Create AWS Glue Data Catalog database and Crawlers.

# change me
ZEPPELIN_DEMO_BUCKET="your-bucket-name"

aws cloudformation create-stack \
    --stack-name zeppelin-crawlers-stack \
    --template-body file://cloudformation/crawler.yml \
    --parameters ParameterKey=ZeppelinDemoBucket,ParameterValue=${ZEPPELIN_DEMO_BUCKET} \
    --capabilities CAPABILITY_NAMED_IAM

Step 4

Configure EMR on Master node.

cd /tmp/zeppelin-emr-demo/
sudo chown -R zeppelin:zeppelin .

# change me
ZEPPELIN_DEMO_BUCKET="your-bucket-name"

sudo aws s3 cp s3://${ZEPPELIN_DEMO_BUCKET}/bootstrap/helium.json \
    /usr/lib/zeppelin/conf/helium.json
sudo chown zeppelin:zeppelin /usr/lib/zeppelin/conf/helium.json

sudo sh /usr/lib/zeppelin/bin/install-interpreter.sh --all

sudo sh /usr/lib/zeppelin/bin/install-interpreter.sh \
    --name "postgres" \
    --artifact org.apache.zeppelin:zeppelin-jdbc:0.8.0

sudo stop zeppelin && sudo start zeppelin

Step 5

Create multi-node EMR cluster.

# change me
ZEPPELIN_DEMO_BUCKET="your-bucket-name"
EC2_KEY_NAME="your-key-name"
LOG_BUCKET="aws-logs-your_aws_account_id-your_region"
GITHUB_ACCOUNT="your-account-name"
GITHUB_REPO="your-new-project-name"
GITHUB_TOKEN="your-token-value"
MASTER_INSTANCE_TYPE="m5.xlarge" # optional
CORE_INSTANCE_TYPE="m5.2xlarge" # optional
CORE_INSTANCE_COUNT=3 # optional

aws cloudformation create-stack \
    --stack-name zeppelin-emr-prod-stack \
    --template-body file://cloudformation/emr_cluster.yml \
    --parameters ParameterKey=ZeppelinDemoBucket,ParameterValue=${ZEPPELIN_DEMO_BUCKET} \
                 ParameterKey=Ec2KeyName,ParameterValue=${EC2_KEY_NAME} \
                 ParameterKey=LogBucket,ParameterValue=${LOG_BUCKET} \
                 ParameterKey=MasterInstanceType,ParameterValue=${MASTER_INSTANCE_TYPE} \
                 ParameterKey=CoreInstanceType,ParameterValue=${CORE_INSTANCE_TYPE} \
                 ParameterKey=CoreInstanceCount,ParameterValue=${CORE_INSTANCE_COUNT} \
                 ParameterKey=GitHubAccount,ParameterValue=${GITHUB_ACCOUNT} \
                 ParameterKey=GitHubRepository,ParameterValue=${GITHUB_REPO} \
                 ParameterKey=GitHubToken,ParameterValue=${GITHUB_TOKEN}

Step 6

Delete multi-node EMR cluster.

aws cloudformation delete-stack --stack-name zeppelin-emr-prod-stack

Run Glue Crawlers.

aws glue start-crawler --name bakery-transactions-crawler
aws glue start-crawler --name movie-ratings-crawler
