---------------------------------

             Summary: Create intelligent defaults for the CrunchCombineFileInputFormat
                 Key: CRUNCH-263
                 URL: https://issues.apache.org/jira/browse/CRUNCH-263
             Project: Crunch
          Issue Type: Bug
          Components: Core, IO
    Affects Versions: 0.8.0
            Reporter: Josh Wills
            Assignee: Josh Wills
             Fix For: 0.8.0
         Attachments: CRUNCH-263.patch

The CombineFileInputFormat is too aggressive at combining file blocks unless a sensible mapred.max.split.size
value is set in the Configuration or is explicitly configured on the CombineFileInputFormat
class itself. This JIRA seeks to set intelligent defaults for the max split size in the case
that a default is not already provided and provide a way for Crunch clients to override the
defaults via a configuration parameter.
