The minimum complement of software packages required to construct a data-fabric cluster. These packages include mapr-core, mapr-core-internal, mapr-cldb, mapr-apiserver, mapr-fileserver, mapr-zookeeper, and others. Note that ecosystem components are not part of core.

To view the "core" packages on a data-fabric cluster, you can use the yum list installed command, as shown in Checking the Core Version.
