Subject [jira] [Created] (ACCUMULO-454) RFile Input Format
Date Fri, 09 Mar 2012 17:10:59 GMT
RFile Input Format

                 Key: ACCUMULO-454
             Project: Accumulo
          Issue Type: New Feature
          Components: client
            Reporter: John Vines
            Assignee: Billie Rinaldi
             Fix For: 1.4.1

We currently provide InputFormats for reading from Accumulo and output formats for both direct
input as well as outputting RFiles. But we provide no mechanism for doing a mapreduce over
existing RFiles, which may be useful for optimizing data flow. We already have input formats
which use RFiles directly for input (The offline input format Keith just finished), but that
still relies on the Accumulo structure. We should go ahead and also create an input format
that just hits RFiles like the other standard file input formats.
