Jie Huang updated HBASE-4364:
-----------------------------
Attachment: hbase-4364-0_94_0.patch
One possible solution for the feature:
1. Add sanityCheck() API in Filter. And call the check function in
getScanner(). So the filter can check the scan and its criteria before hand.
2. In SingleColumnValueFilter, if the tested set doesn't include the criteria
column, add it in sanityCheck(). Afterwards, remove the column in
filterRow(kv), so that the user will get all required columns.
I will add one corresponding testcase and do the verification later. Any
comment, please let me know. thanks.
> Filters applied to columns not in the selected column list are ignored

> other columns which aren't selected, then those filter conditions are ignored.
