Aaron T. Myers created HDFS-8193: ------------------------------------ Summary: Add the ability to delay replica deletion for a period of time Key: HDFS-8193 URL: https://issues.apache.org/jira/browse/HDFS-8193 Project: Hadoop HDFS Issue Type: New Feature Components: namenode Affects Versions: 2.7.0 Reporter: Aaron T. Myers Assignee: Zhe Zhang
When doing maintenance on an HDFS cluster, users may be concerned about the possibility of administrative mistakes or software bugs deleting replicas of blocks that cannot easily be restored. It would be handy if HDFS could be made to optionally not delete any replicas for a configurable period of time. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
