setDatanodeRestartInterval(interval)

interval is a non-negative integer (in seconds).

Modify datanodeRestartInterval online. This command can only be executed by an administrator on the controller.

• If interval=0, the controller will not automatically restart the data/compute node.

• If interval>0, the controller will restart the data/compute node after datanodeRestartInterval of offline time.

Note: The modified configuration is only valid for the current node, and will expire after the system restarts. To make it permanent, please change the configuration parameter datanodeRestartInterval.
