[jira] [Resolved] (HBASE-11210) Consider restoring Filter class back to an interface

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

     [ https://issues.apache.org/jira/browse/HBASE-11210?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

stack resolved HBASE-11210.
---------------------------

    Resolution: Invalid

bq. I am expecting Lars Hofhansl to comment on this issue.

Resolving as invalid. The filer expects someone else is to provide justification (see above) OR, the justification is some larger project around hasFilterRow that HBASE-10965 is related to. And this is after two petitions by two separate committers trying to get clarity around why this issue needs to exist.

> In 0.94, Filter class is an interface.
> From Filter.java in 0.96 :
> {code}
>  * Interface for row and column filters directly applied within the regionserver.
> ...
>  * When implementing your own filters, consider inheriting {@link FilterBase} to help
>  * you reduce boilerplate.
> {code}
> We should consider restoring Filter class back to an interface.
> Lars first brought up this notion:
> https://issues.apache.org/jira/browse/HBASE-6657?focusedCommentId=13456317&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13456317
> This gives users / developers clear suggestion that custom filters should override FilterBase instead of implementing Filter directly.
> Thanks to Anoop who acknowledged this idea during offline discussion.
