Integration with Hadoop distributions

If you deploy HDFS transparency with a Hadoop distribution, such as IBM® BigInsights® IOP or HortonWorks HDP, configure the native HDFS NameNode as the HDFS Transparency NameNode and configure native HDFS DataNodes as HDFS Transparency DataNodes. Add these nodes into IBM Storage Scale cluster. This setup results in fewer configuration changes. Therefore, before installing Hadoop distribution, you need to plan the nodes as NameNode and the nodes as DataNodes.

If the HDFS Transparency NameNode is not the same as the native HDFS NameNode, some services might fail to start and can require additional configuration changes.
