Subject [jira] [Updated] (HBASE-8847) Filter.transform() always applies unconditionally, even when combined in a FilterList
Date Tue, 02 Jul 2013 17:29:21 GMT

     [ https://issues.apache.org/jira/browse/HBASE-8847?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Christophe Taton updated HBASE-8847:
------------------------------------

    Attachment: HBASE-8847.base=trunk.diff

Here is a new patch based on trunk that includes:
 - a unit-test in FilterList, to exercise transform() with KeyOnlyFilter.
 - updated javadoc in Filter to document transform().

> FilterList.transform() applies all transformation from all filters unconditionally.
> This leads to surprising results, eg. with combinations such as
>   (family=X and column=Y and KeyOnlyFilter) or ...
> The KeyOnlyFilter will strip the values from all KeyValues.
