[zebra] TableRecordReader.getProcess method only returns 0 or 1
---------------------------------------------------------------

                 Key: PIG-1208
                 URL: https://issues.apache.org/jira/browse/PIG-1208
             Project: Pig
          Issue Type: Bug
    Affects Versions: 0.6.0
            Reporter: Yan Zhou
            Assignee: Yan Zhou


M/R requires more accurate progress status. It should be based on number of rows. For unsorted
tables, this data is readily available as each mapper calculates the number of rows based
upon its split. However, for sorted tables, this number of rows is not used and therefore
will need to be calculated from the TFile scanner working on a key range. This TFile functionality
is unfortunately unavailable now and will be needed to support this functionality.
