Subject [jira] Created: (MAPREDUCE-1910) Allow raid policy to specify a parent policy
Date Thu, 01 Jul 2010 23:59:50 GMT
Allow raid policy to specify a parent policy
--------------------------------------------

                 Key: MAPREDUCE-1910
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-1910
             Project: Hadoop Map/Reduce
          Issue Type: New Feature
          Components: contrib/raid
    Affects Versions: 0.22.0
            Reporter: Scott Chen
            Assignee: Scott Chen
            Priority: Minor
             Fix For: 0.22.0


We encountered the problem that there are lots of redundancy in our raid.xml file. Most of
the policy shares the same properties. It will be nice if a policy can inherit from a previously
defined policy and get the default properties from it. This way it is easier to maintain the
raid policies.
