Execute the Disk Balancer plan
For a DataNode, the HDFS Disk Balancer moves data according to the details specified in the JSON document generated as the Disk Balancer plan.
You must have generated the data movement plan for the
DataNode.
Run the
hdfs diskbalancer -execute
command by specifying the
path to the JSON plan document.
hdfs diskbalancer -execute
/system/diskbalancer/<Creation_Timestamp>/nodename.plan.json
The command reads the DataNode's address from the JSON file and executes the plan.
