Target Version/s: (was: 2.8.0)
> Balancer configures DN properties
> -
>
> Key: HDFS-10294
> URL: https://issues.apache.org/jira/browse/HDFS-10294
> Project: Hadoop HDFS
> Issue Type: Sub-task
> Components: balancer & mover
>Affects Versions: 2.6.0
>Reporter: John Zhuge
>Assignee: John Zhuge
>
> Balancer configures the 2 balance-related properties (bandwidthPerSec and
> concurrentMoves) using NN API {{get/setBalancerBandwidth}} and the new
> {{get/setBalancerConcurrentMoves}}.
> Details:
> * Upon the start of the balancer, set the DN properties.
> * Use NN API to query and set the 2 properties. 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.
