streaming
Consumes messages from a Amazon Kinesis streams and does wordcount.
Usage: KinesisWordProducerASL <stream-name> <endpoint-url> \ <records-per-sec> <words-per-record>
Usage: KinesisWordProducerASL <stream-name> <endpoint-url> \ <records-per-sec> <words-per-record>
<stream-name> is the name of the Kinesis stream (ie. mySparkStream) <endpoint-url> is the endpoint of the Kinesis service (ie. https://kinesis.us-east-1.amazonaws.com) <records-per-sec> is the rate of records per second to put onto the stream <words-per-record> is the rate of records per second to put onto the stream
Example: $ SPARK_HOME/bin/run-example streaming.KinesisWordProducerASL mySparkStream \ https://kinesis.us-east-1.amazonaws.com us-east-1 10 5
Consumes messages from a Amazon Kinesis streams and does wordcount.
This example spins up 1 Kinesis Receiver per shard for the given stream. It then starts pulling from the last checkpointed sequence number of the given stream.
Usage: KinesisWordCountASL <app-name> <stream-name> <endpoint-url> <region-name> <app-name> is the name of the consumer app, used to track the read data in DynamoDB <stream-name> name of the Kinesis stream (ie. mySparkStream) <endpoint-url> endpoint of the Kinesis service (e.g. https://kinesis.us-east-1.amazonaws.com)
Example: # export AWS keys if necessary $ export AWS_ACCESS_KEY_ID=<your-access-key> $ export AWS_SECRET_KEY=<your-secret-key>
# run the example $ SPARK_HOME/bin/run-example streaming.KinesisWordCountASL myAppName mySparkStream \ https://kinesis.us-east-1.amazonaws.com
There is a companion helper class called KinesisWordProducerASL which puts dummy data onto the Kinesis stream.
This code uses the DefaultAWSCredentialsProviderChain to find credentials in the following order: Environment Variables - AWS_ACCESS_KEY_ID and AWS_SECRET_KEY Java System Properties - aws.accessKeyId and aws.secretKey Credential profiles file - default location (~/.aws/credentials) shared by all AWS SDKs Instance profile credentials - delivered through the Amazon EC2 metadata service For more information, see http://docs.aws.amazon.com/AWSSdkDocsJava/latest/DeveloperGuide/credentials.html
