Announcing: MapR Expansion Pack (MEP) 4.0 Released

Date: Nov. 21st, 2017


We’re pleased to announce the general release of the MapR Expansion Pack (MEP) version 4.0.


MapR Expansion Packs are an expanded version of the MapR Ecosystem Pack (MEP) which is a way to deliver ecosystem upgrades decoupled from core platform upgrades. This expansion means that we can also deliver some core functionality in faster way using the framework we put together for Ecosystem projects to allow you to upgrade independently of your core platform.


MEP 4.0 is the first MEP for the MapR 6.0 release train and there's a lot of new content to support the new 6.0 initiatives including security enhancements for all ecosystem and feature-complete language bindings for MapR-DB OJAI.


Key Features


Security Enhancements

MEP 4.0 is designed to have security enabled with a single click. This means that most wire-level encryption and authentication for network-based connections are automatically enabled for new clusters, delivering an innovative approach to simplified security.
MapR installer has a simple Enable Security check box which will ensure that the platform and required ecosystem components are configured properly. If you're using manual install, 'configure.sh –secure' has been enhanced to enable security for platform and ecosystem at once.
