Subject [jira] Created: (HADOOP-5169) the map output servlet should only locate the index if it isn't in the cache
Date Wed, 04 Feb 2009 21:19:59 GMT
the map output servlet should only locate the index if it isn't in the cache
----------------------------------------------------------------------------

                 Key: HADOOP-5169
                 URL: https://issues.apache.org/jira/browse/HADOOP-5169
             Project: Hadoop Core
          Issue Type: Improvement
          Components: mapred
            Reporter: Owen O'Malley
            Assignee: Owen O'Malley


Currently, the map output servlet locates the cache file using the local dir allocator, before
it determines whether the information is in the cache. It would avoid a lot of filesystem
lookups if it waited.
