What's New in Apache Hadoop Ozone

This topic lists new features for Apache Hadoop Ozone in this release of Cloudera Runtime..

Support for Recon web user interface

Recon is a centralized monitoring and management service within an Ozone cluster that provides information about the metadata maintained by different Ozone components such as the Ozone Manager (OM) and the Storage Container Manager (SCM). Recon keeps track of the metadata as the cluster is operational, and displays the relevant information through a dashboard and different views on the Recon web user interface. This information helps in understanding the overall state of the Ozone cluster.

For more information, see Working with Recon web user interface

Support for High Availability of Ozone Manager

Configuring High Availability (HA) for the Ozone Manager (OM) enables you to run redundant Ozone Managers on your Ozone cluster and prevents the occurrence of a single point of failure in the cluster from the perspective of namespace management.
