Ted Yu commented on HBASE-7481:

If you search https://builds.apache.org/job/PreCommit-HBASE-Build/4869/console for '(Test',
you would see:

'mvn site' warning appears for every patch, so I would not worry about it.

> Currently there is no way to throw custom IOExceptions from any of the filter methods.
> For implementers of custom filters that presents a problem.
> For example there are scenarios where the filter would want to indicate to the client
that there it should not retry. Currently there is no way of doing that.
