Tungsten Replicator 3.0 is Cloudera Enterprise 5 Certified

One of the key platforms I’ve been testing on for the MySQL to Hadoop replication has been Cloudera, largely driven by customer requirements, but it’s also one of the easiest way to get started with Hadoop.

What I’m even more pleased about is the fact that we are proud to announce that Tungsten Replicator 3.0 is certified for use on the new Cloudera Enterprise 5 platform. That means that we’re sure that replicating your data from MySQL to Cloudera 5 and have it work without causing problems or difficulties on the Hadoop loading and materialisation.

The actual performance and process is unchanged; you just use a different JS-based batchloader script to work with different tools.

Robert has also been simplifying some of the core functionality, such as configuring some fixed pre-determined formats, so you no longer have to explicitly set the field and record separators.
