You can use the Apache Spark Driver for Arm Treasure Data (td-spark) on Amazon Elastic MapReduce (EMR). Although we recommend using the us-east region of Amazon EC2 for the optimal performance, it can also be used in other Spark environments as well.

Overview

TD Spark Release Notes
TD Spark FAQs
- General usage of td-spark

What does the driver enable today?

Enable accessing Treasure Data from Spark in Scala and Python (PySpark).
Pull Treasure Data tables into Spark as a DataFrame (No TD query is issued, providing the shortest latency path between TD stored data & your spark cluster possible).
Issue Presto, Hive, or SparkSQL queries and return the result as a Spark DataFrame.

This driver is recommended for use with Spark 2.1.0 or higher

Recommendations regarding use

For fastest data access, and lowest data transfer costs, we recommend that you set-up your spark cluster in the AWS us-east region. Data Transfer costs may become quite high if using other AWS regions or processing environments.

TD Spark Driver on EMR

Create an EMR Spark cluster

Create an EMR cluster with Spark support. Using us-east region is highly recommended to maximize data transfer performance from S3.
Check the master node address of the new EMR

If you created EMR with default security group (ElasticMapReduce-master), make sure to permit inbound access from your environment. See “Amazon EMR-Managed Security Groups”.

Set Up TD Spark Integration

Download td-spark jar file:

[hadoop@ip-x-x-x-x]$ wget https://s3.amazonaws.com/td-spark/td-spark-assembly_2.11-0.4.0.jar

Create a td.conf file in the master node:

# Describe your TD API key here
spark.td.apikey=(your TD API key)
# (recommended) this use KryoSerializer for faster performance
spark.serializer=org.apache.spark.serializer.KryoSerializer

Using spark-shell on EMR

[hadoop@ip-x-x-x-x]$ spark-shell --master yarn --jars td-spark-assembly-latest.jar --properties-file td.conf
