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

["Billy Pearson (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HBASE-1170?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12679669#action_12679669 ] 

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.

> 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.
