What’s New in RapidMiner Radoop 2.4?
This page describes the enhancement being delivered by RapidMiner Radoop 2.4.
Improved connection setup experience, new tests and error messages
Connection tests to the Hadoop cluster have improved and now provide more detail on potential issues. Tests include checking for networking problems, missing High Availability configurations, and more. The connection dialog now provides more details for determining the root cause of an integration problem.
The new release supports connection to the latest Hortonworks distribution (version 2.3) and continues to support the latest Cloudera and Amazon releases. Additionally, it automates a large part of the connection setup so that no manual steps are required to connect to a cluster with default settings and default networking. Connection to VMs that some of the vendors provide is also now possible.
RapidMiner Radoop 2.4 additionally provides several fixes and workarounds for Hadoop bugs in different distribution versions. The cleanup of various temporary objects is now more reliable.
