Qubole Release Notes 11-Aug-2016

Release Version: 35.3.0

For details of what has changed in this version of QDS, see What is New and List of Changes and Bug Fixes in this Release.


What is New

Support for Heterogeneous Spot Nodes on Hadoop 2 and Spark Clusters

Qubole now supports heterogeneous instances types on spot nodes too. This is after enabling the heterogeneous feature using the API. See Heterogeneous Nodes for more information. This feature is highly beneficial when either the spot price of primary slave type is higher than
the spot price specified in the cluster configuration or the requested number of spot nodes cannot be granted by AWS at that point of time.

This feature is also supported with IAM roles.
