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

stack commented on HBASE-11210:
-------------------------------

Please fix the description or close.  As is, it makes no sense.

Why does going back to an Interface force use of FilterBase?  Why force use of FilterBase at all? 

"consider inheriting" does not mean "should override".

> 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.
> 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.
