Erik Krogen commented on HDFS-14979: ------------------------------------ Committed this down to branch-2.10 (trunk, branch-3.2, branch-3.1, branch-2, branch-2.10). Wasn't sure if I should do branch-2 given that I think we've decided 2.10 is the last 2.x release, but figured it couldn't hurt. > [Observer Node] Balancer should submit getBlocks to Observer Node when > possible > ------------------------------------------------------------------------------- > > Key: HDFS-14979 > URL: https://issues.apache.org/jira/browse/HDFS-14979 > Project: Hadoop HDFS > Issue Type: Improvement > Components: balancer & mover, hdfs > Reporter: Erik Krogen > Assignee: Erik Krogen > Priority: Major > Attachments: HDFS-14979.000.patch > > > In HDFS-14162, we made it so that the Balancer could function when > {{ObserverReadProxyProvider}} was in use. However, the Balancer would still > read from the active NameNode, because {{getBlocks}} wasn't annotated as > {{@ReadOnly}}. This task is to enable the Balancer to actually read from the > Observer Node to alleviate load from the active NameNode. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
