    Description

      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.
