This section describes using Red Hat configurations to support high availability.
This document is intended for system administrators for configuring the Hadoop NameNode (NN) and JobTracker (JT) service for High Availability and also for configuring clients and other Hadoop services to be resilient while the NameNode or JobTracker fails over.
The Hortonworks Data Platform (HDP) High Availability (HA) kit for Red Hat Enterprise Linux (RHEL) provides enterprise grade high availability of the NameNode Service as part of the HDP cluster.
To learn more, see HDP's Full-Stack HA Architecture.
