Classic Clusters

You can use the Classic Clusters panel of the Overview page to view the total number of clusters enabled for Replication Manager, the number that are in a error state, the number that are active, and the number of clusters for which a warning is issued.

You can investigate the issues associated with clusters that have an error or warning status by navigating to Ambari web UI incase of HDP on-premise clusters and Cloudera Manager UI for CDH on-premise clusters.

If this value is greater than zero, you can click the number to open a table that displays the cluster name and remaining capacity.

Total

Error
