Junping Du updated HDFS-6122: ----------------------------- Target Version/s: (was: 2.8.0) > Rebalance cached replicas between datanodes > ------------------------------------------- > > Key: HDFS-6122 > URL: https://issues.apache.org/jira/browse/HDFS-6122 > Project: Hadoop HDFS > Issue Type: Improvement > Components: caching > Affects Versions: 2.3.0 > Reporter: Andrew Wang > Assignee: Andrew Wang > > It'd be nice if the NameNode was able to rebalance cache usage among > datanodes. This would help avoid situations where the only three DNs with a > replica are full and there is still cache space on the rest of the cluster. > It'll also probably help for heterogeneous node sizes and when adding new > nodes to the cluster or doing a rolling restart. -- 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
