Subject [jira] Commented: (HBASE-1829) Make use of start/stop row in TableInputFormat
Date Tue, 10 Nov 2009 18:27:28 GMT

    [ https://issues.apache.org/jira/browse/HBASE-1829?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12775987#action_12775987

Lars George commented on HBASE-1829:
------------------------------------

v5 patch is on top of v4 patch, in other words v5 only has the diff after v4 is applied. Does
that make sense?

> Since we can now specify a start and stop row with the Scan that is handed to the TIF
we can reduce the splits to the regions that contain these rows. That allows to test large
MR jobs on a single region for example.
