Replacing a Permanently Failed Node

The DC/OS HDFS Service is resilient to temporary node failures. However, if a DC/OS agent hosting a HDFS node is permanently lost, manual intervention is required to replace the failed node. The following command should be used to replace the node residing on the failed server.

$ dcos hdfs --name=<service-name> pods replace <node_id>

Restarting a Node

If you must forcibly restart a node, use the following command to restart the node on the same agent node where it currently resides. This will not result in an outage or loss of data.

$ dcos hdfs --name=<service-name> pods restart <node_id>
