Junping Du updated HDFS-10294: ------------------------------ 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
