Configuring and running the HDFS balancer using Cloudera Manager

Learn how to run HDFS Balancer by using Cloudera Manager. You configure the balancer threshold, concurrent moves, and block size. Then you run the HDFS Balancer. You also learn about recommended values for the HDFS Balancer.

In Cloudera Manager, the HDFS balancer utility is implemented by the Balancer role. The Balancer role usually shows a health of None on the HDFS Instances tab because it does not run continuously.

The Balancer role is normally added (by default) when the HDFS service is installed. If it has not been added, you must add a Balancer role to rebalance HDFS and to see the Rebalance action.
