How can I put data records into a Kinesis data stream using the KPL?

Short description

To put a record into a Kinesis data stream using the KPL, you must meet the following requirements:

• You have a running Amazon Elastic Compute Cloud (Amazon EC2) Linux instance.
• An AWS Identity and Access Management (IAM) role is attached to your instance.
• The KinesisFullAccess policy is attached to the instance's IAM role.

Resolution

To put records into a Kinesis data stream using the KPL:

1.    Connect to your Linux instance.

2.    Install the latest version of the OpenJDK 8 developer package:

sudo yum install java-1.8.0-openjdk-devel

3.    Confirm that Java is installed:

java -version

The expected output looks like this:

java version "1.7.0_181"
OpenJDK Runtime Environment (amzn-2.6.14.8.80.amzn1-x86_64 u181-b00)
OpenJDK 64-Bit Server VM (build 24.181-b00, mixed mode)

4.    Run the following commands to set Java 1.8 as the default java and javac providers:

sudo /usr/sbin/alternatives --config java 
sudo /usr/sbin/alternatives --config javac

5.    Add a repository with an Apache Maven package:

sudo wget http://repos.fedorapeople.org/repos/dchen/apache-maven/epel-apache-maven.repo -O /etc/yum.repos.d/epel-apache-maven.repo

6.    Set the version number for the Maven packages:

sudo sed -i s/\$releasever/6/g /etc/yum.repos.d/epel-apache-maven.repo

7.    Use yum to install Maven:

sudo yum install -y apache-maven

8.    Confirm that Maven is installed properly:

mvn -version

The expected output looks like this:

Apache Maven 3.5.2 (138edd61fd100ec658bfa2d307c43b76940a5d7d; 2017-10-18T07:58:13Z)
Maven home: /usr/share/apache-maven
Java version: 1.7.0_181, vendor: Oracle Corporation
Java home: /usr/lib/jvm/java-1.7.0-openjdk-1.7.0.181.x86_64/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "linux", version: "4.14.33-51.37.amzn1.x86_64", arch: "amd64", family: "unix"

9.    Install git, and then download the KPL from Amazon Web Services - Labs:

sudo yum install git
git clone https://github.com/awslabs/amazon-kinesis-producer

10.    Open the amazon-kinesis-producer/java/amazon-kinesis-producer-sample/ directory, and then list the files:

cd amazon-kinesis-producer/java/amazon-kinesis-producer-sample/
ls
default_config.properties  pom.xml  README.md  src  target

11.    Run a command similar to the following to create a Kinesis data stream:

aws kinesis create-stream --stream-name kinesis-kpl-demo --shard-count 2

For more information about the number of shards needed, see Resharding, scaling, and parallel processing.

12.    Run list-streams to confirm that the stream was created:

aws kinesis list-streams

13.    Open the SampleProducer.java file on the Amazon Web Services - Labs GitHub repository, and then modify the following fields:
For public static final String STREAM_NAME_DEFAULT, enter the name of the Kinesis data stream that you previously created.
For public static final String REGION_DEFAULT, enter the Region that you're using.

Example:

cd src/com/amazonaws/services/kinesis/producer/sample
vi SampleProducerConfig.java

public static final String STREAM_NAME_DEFAULT = "kinesis-kpl-demo";
public static final String REGION_DEFAULT = "us-east-1";

14.    Run the following command in the amazon-kinesis-producer-sample directory to allow Maven to download all of the directory's dependencies:

mvn clean package

15.    Run the following command in the amazon-kinesis-producer-sample directory to run the producer and to send data into the Kinesis data stream:

mvn exec:java -Dexec.mainClass="com.amazonaws.services.kinesis.producer.sample.SampleProducer"

16.    Check the Incoming Data (Count) graph on the Monitoring tab of the Kinesis console to verify the number of records sent to the stream.

Note: The record count might be lower than the number of records sent to the data stream. This lower record count can occur because the KPL uses aggregation.
