Andrew Wang created HDFS-11023: ---------------------------------- Summary: I/O based throttling of DN replication work Key: HDFS-11023 URL: https://issues.apache.org/jira/browse/HDFS-11023 Project: Hadoop HDFS Issue Type: Sub-task Components: erasure-coding Affects Versions: 3.0.0-alpha1 Reporter: Andrew Wang
Datanode recovery work is currently throttled based on the number of blocks to be recovered. This is fine in a replicated world, since each block is equally expensive to recover. However, EC blocks are much more expensive to recover, and the amount depends on the EC policy. It'd be better to have recovery throttles that accounted for the amount of I/O rather than just the # of blocks. -- 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
