Welcome to the User Guide for WANdisco's WD Fusion.
1. What is WD Fusion?
WD Fusion is a software application that allows Hadoop deployments to replicate HDFS data between Hadoop clusters that are running different, even incompatible versions of Hadoop. It is even possible to replicate between different vendor distributions and versions of Hadoop.
- Virtual File System for Hadoop, compatible with all Hadoop applications.
- Single, virtual Namespace that integrates storage from different types of Hadoop, including CDH, HDP, EMC Isilon, Amazon S3/EMRFS and MapR.
- Storage can be globally distributed.
- WAN replication using WANdisco's patented active-active replication technology, delivering single-copy consistent hdfs data, replicated between far-flung data centers.
