Subject [jira] Created: (HADOOP-5262) Allow specifying min shares as percentage of cluster
Date Sat, 14 Feb 2009 08:11:59 GMT
Allow specifying min shares as percentage of cluster
----------------------------------------------------

                 Key: HADOOP-5262
                 URL: https://issues.apache.org/jira/browse/HADOOP-5262
             Project: Hadoop Core
          Issue Type: New Feature
          Components: contrib/fair-share
            Reporter: Matei Zaharia
            Priority: Minor


Currently the guaranteed shares for pools in the fair scheduler are specified as a number
of slots. For organizations where a group pays X% of the cluster and the actual number of
nodes in the cluster varies due to failures, expansion, etc over time, it would be useful
to support a guaranteed share given as a percentage too. This would just let you write in
the config file something like <minMaps>5%</minMaps> instead of <minMaps>42</minMaps>.
The scheduler would need to recompute what this means in terms of number of slots on every
update (probably through some kind of update(ClusterStatus) method in PoolManager).
