Zhan Zhang commented on HBASE-14795:
------------------------------------

[~jmhsieh] My patch in HBASE-14849 will not fix those three warning. But I checked again and
think these warning are not generated by the patch of this JIRA, because the patch does not
touch any pom.xml file but the warning is actually scoping issue in pom.xml. Correct me if
I am wrong. Please following for details.

> This is a sub-jira of HBASE-14789.  This jira is to focus on the replacement of TableInputFormat
for a more custom scan implementation that will make the following use case more effective.
> Use case:
> In the case you have multiple scan ranges on a single table with in a single query. 
TableInputFormat will scan the the outer range of the scan start and end range where this
implementation can be more pointed.
