             Summary: Attempt to estimate HBase table sizes when we're given a trivial Scan
object
                 Key: CRUNCH-230
                 URL: https://issues.apache.org/jira/browse/CRUNCH-230
             Project: Crunch
          Issue Type: Improvement
          Components: IO
    Affects Versions: 0.6.0
            Reporter: Josh Wills
            Priority: Minor
         Attachments: CRUNCH-230.patch

If we're asked to do a scan of an entire HBase table, we can actually do a pretty good job
of estimating how large it is by looking up its directory in HDFS. This patch checks the input
scan given to the HBaseSourceTarget, and if it doesn't specify any filters, looks up the size
of the input table on HDFS.
