Make DN minimum valid volumes configurable ------------------------------------------
Key: HDFS-1161 URL: https://issues.apache.org/jira/browse/HDFS-1161 Project: Hadoop HDFS Issue Type: Improvement Components: data-node Affects Versions: 0.22.0 Reporter: Eli Collins Assignee: Eli Collins Fix For: 0.22.0 The minimum number of non-faulty volumes to keep the DN active is hard-coded to 1. It would be useful to allow users to configure this value so the DN can be taken offline when eg half of its disks fail, otherwise it doesn't get reported until it's down to it's final disk and suffering degraded performance. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
