Selective Node Repair for SDX (Data Lake)

Cloudera Employee

Management Console now allows you to select specific nodes within a node group to include a repair operation.. This will reduce the downtime incurred if only a subset of the nodes are unhealthy.  

 

The CDP Management Console has always provided the ability to repair nodes, but this has been at a host group level. With the recent addition of Medium Duty SDX clusters, this would result in the repair operation happening on both healthy and unhealthy nodes, resulting in a service outage while the repair operation was in progress.  

 

From the Hardware tab of the Data Lake details, you can click the Repair icon to select specific nodes within a host group to repair.

 

For details on what happens during the repair process, please see the documentation on Data Lake Repair.
