This jira proposes to add a Comparable > Metric interface from which DatanodeCapacity and DatanodeIOLoad metrics can > be derived. This will also convert SCM Container Placement Capacity policy to > use these metrics. > Adding these metrics makes all placement policy operate on the basis of these > metrics and it makes it easy to simulate cluster imbalances as well as reason > about code. All new SCM metrics which have the property of total ordering > should be derived from this interface. -- This message was sent by Atlassian JIRA (v6.3.15#6346) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
