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.
