Issue Time Tracking ------------------- Worklog Id: (was: 778059) Remaining Estimate: 0h Time Spent: 10m > EC: Improve performance of decommissioning dn with many ec blocks > ----------------------------------------------------------------- > > Key: HDFS-16613 > URL: https://issues.apache.org/jira/browse/HDFS-16613 > Project: Hadoop HDFS > Issue Type: Improvement > Components: ec, erasure-coding, namenode > Affects Versions: 3.4.0 > Reporter: caozhiqiang > Assignee: caozhiqiang > Priority: Major > Time Spent: 10m > Remaining Estimate: 0h > > In a hdfs cluster with a lot of EC blocks, decommission a dn is very slow. > The reason is unlike replication blocks can be replicated from any dn which > has the same block replication, the ec block have to be replicated from the > decommissioning dn. > The configurations dfs.namenode.replication.max-streams and > dfs.namenode.replication.max-streams-hard-limit will limit the replication > speed, but increase these configurations will create risk to the whole > cluster's network. So it should add a new configuration to limit the > decommissioning dn, distinguished from the cluster wide max-streams limit. -- This message was sent by Atlassian Jira (v8.20.7#820007) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
