[jira] Created: (HBASE-1170) Specify startRow and stopRow for MapReduce / TabieInputFormat

Specify startRow and stopRow for MapReduce / TabieInputFormat
-------------------------------------------------------------

                 Key: HBASE-1170
                 URL: https://issues.apache.org/jira/browse/HBASE-1170
             Project: Hadoop HBase
          Issue Type: New Feature
          Components: mapred
            Reporter: Jonathan Gray
            Assignee: Jonathan Gray
             Fix For: 0.19.1, 0.20.0


We have a use case for this.  Can currently be implemented using filters but this still requires a full table scan.

In addition to extending TableMapReduceUtil, this would affect the splitting algorithm to only include those regions containing keys within the start and stop.

[jira] Commented: (HBASE-1170) Specify startRow and stopRow for MapReduce / TabieInputFormat

Billy Pearson commented on HBASE-1170:
--------------------------------------

I thank we should have three options for this in TableMapReduceUtil

startRow only
stopRow only
startRow & stopRow

with that there should not be many reasons not use it and it would be more complete.
