Step 5: Copy data to DynamoDB

In this step, you will copy data from the Hive table (hive_features) to a new table in DynamoDB.

  1. Open the DynamoDB console at

  2. Choose Create Table.

  3. On the Create DynamoDB table page, do the following:

    1. In Table, type Features.

    2. For Primary key, in the Partition key field, type Id. Set the data type to Number.

      Clear Use Default Settings. For Provisioned Capacity, type the following:

      • Read Capacity Units10

      • Write Capacity Units10

    Choose Create.

  4. At the Hive prompt, enter the following HiveQL statement:

    CREATE EXTERNAL TABLE ddb_features (feature_id BIGINT, feature_name STRING, feature_class STRING, state_alpha STRING, prim_lat_dec DOUBLE, prim_long_dec DOUBLE, elev_in_ft BIGINT) STORED BY 'org.apache.hadoop.hive.dynamodb.DynamoDBStorageHandler' TBLPROPERTIES( "" = "Features", "dynamodb.column.mapping"="feature_id:Id,feature_name:Name,feature_class:Class,state_alpha:State,prim_lat_dec:Latitude,prim_long_dec:Longitude,elev_in_ft:Elevation" );

    You have now established a mapping between Hive and the Features table in DynamoDB.

  5. Enter the following HiveQL statement to import data to DynamoDB:

    INSERT OVERWRITE TABLE ddb_features SELECT feature_id, feature_name, feature_class, state_alpha, prim_lat_dec, prim_long_dec, elev_in_ft FROM hive_features;

    Hive will submit a MapReduce job, which will be processed by your Amazon EMR cluster. It will take several minutes to complete the job.

  6. Verify that the data has been loaded into DynamoDB:

    1. In the DynamoDB console navigation pane, choose Tables.

    2. Choose the Features table, and then choose the Items tab to view the data.
