When using DynamoDBMetadataStore with a insert heavy hive app , it started throwing exceptions in DynamoDBMetadataStore::move. But just with the following exception, it is relatively hard to debug on the real issue in DynamoDB side.

Caused by: com.amazonaws.services.dynamodbv2.model.AmazonDynamoDBException: 1 validation error detected: Value '{ddb-table-name-334=[com.amazonaws.dynamodb.v20120810.WriteRequest@ca1da583, com.amazonaws.dynamodb.v20120810.WriteRequest@ca1fc7cd, com.amazonaws.dynamodb.v20120810.WriteRequest@ca4244e6, com.amazonaws.dynamodb.v20120810.WriteRequest@ca2f58a9, com.amazonaws.dynamodb.v20120810.WriteRequest@ca3525f8,
