There might be a slight delay for the property changes to be propagated to all DNs. > * The DN property changes will not survive restart. > * Balancer gets the property values from command line or its config file. > * No need to edit the config file on each DN or run {{hdfs dfsadmin -setBalancerBandwidth}} to configure every DN in the cluster. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
