VectorH uses HDFS as the storage layer for data and calls on other Hadoop services such as the NameNode and YARN. VectorH is agnostic to the Hadoop distribution used.

A supported Hadoop distribution must be installed and running for VectorH to operate. Supported versions of Hadoop distributions and underlying operating systems are described in the Product Availability Matrix ( http://downloads.actian.com/media/PDFs/Product_Avail_Matrix_Vector.pdf).
