I have to process some data which is persisted in Amazon Dynamo DB using Hadoop map reduce.
I was searching over internet for Hadoop InputFormat for Dynamo DB and couldn’t find it. I’m not familiar with Dynamo DB so I’m guessing there is some trick related to DynamoDB and Hadoop? If there is anywhere implementation of this Input Format could you please share it?
After a lot of searching I found DynamoDBInputFormat and DynamoDBOutputFormat in one of Amazon’s libraries.
On amazon elastic map reduce there is library called hive-bigbird-handler which contains input and output format for dynamoDB.
Full class names are: org.apache.hadoop.hive.dynamodb.write.DynamoDBOutputFormat and org.apache.hadoop.hive.dynamodb.read.DynamoDBInputFormat
I hope these classes will be useful to community.
