Subject [jira] [Created] (ACCUMULO-712) InputFormat that supports more than one tablet per input split if on the same tablet server
Date Thu, 02 Aug 2012 04:20:02 GMT
Jim Donofrio created ACCUMULO-712:
-------------------------------------

             Summary: InputFormat that supports more than one tablet per input split if on
the same tablet server
                 Key: ACCUMULO-712
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-712
             Project: Accumulo
          Issue Type: New Feature
          Components: client
            Reporter: Jim Donofrio
            Assignee: Billie Rinaldi


Similar to CombineFileInputFormat for hdfs files, there should be an InputFormat that supports
more than one tablet per input split if on the same tablet server. This should also work with
ACCUMULO-391 to allow adding tablets from different compatible tables into a single input
split. This allows mappers that finish very quickly to have more work to do. This could be
a new InputFormat that extends AccumuloInputFormat or an option added to AccumuloInputFormat.
