Zach York commented on HBASE-19356:
-----------------------------------
I'm a fan of default implementations for this like what [~appy] did for the
coprocessor interfaces in HBASE-17312
> Provide delegators and base implementation for Phoenix implemented interfaces
> -----------------------------------------------------------------------------

> Key: HBASE-19356
> URL: https://issues.apache.org/jira/browse/HBASE-19356
> Project: HBase
> Issue Type: Improvement
> Reporter: James Taylor
>
> Many of the changes Phoenix needs to make for various branches to support
> different versions of HBase are due to new methods being added to interfaces.
> Often times Phoenix can use a noop or simply needs to add the new method to
> it's delegate implementor. It'd be helpful if HBase provided base
> implementations and delegates that Phoenix could use instead. Here are some
> that come to mind:
> - RegionScanner
> - HTableInterface (Table interface now?)
> - RegionObserver
> There are likely others that [~rajeshbabu], [[email protected]], and
> [~elserj] would remember.
