Update : Read-replica support for Apache HBase on S3 and Apache Flink 1.3.0 in Amazon EMR release 5.7.0

You can now create read-replica Apache HBase clusters pointed to the same underlying HBase tables in Amazon S3 on Amazon EMR release 5.7.0. Apache HBase is a distributed, non-relational database built for random, strictly consistent realtime access for tables with billions of rows and millions of columns. By using read-replicas, you can increase availability by creating HBase clusters in different Amazon EC2 Availability Zones that read from the same dataset in Amazon S3.
