Improvements for S3DistCp This release changes the file names generated by the --groupBy parameter of S3DistCp. In addition, you no longer need to specify --groupBy and --srcPattern simultaneously. For more information, go to Distributed Copy Using S3DistCp.
Hive 0.7.1.2 Amazon Elastic MapReduce supports Hive 0.7.1.2. Hive 0.7.1.2 modifies the way files are named in Amazon S3 for dynamic partitions. It prepends file names in Amazon S3 for dynamic partitions with a unique identifier. Using Hive 0.7.1.2 you can run queries in parallel with set hive.exec.parallel=true. It also fixes an issue with filter pushdown when accessing Amazon DynamoDB with spare data sets.For more information, go to Configuring Hive.
