Subject [jira] [Commented] (HBASE-19356) Provide delegators and base implementation for Phoenix implemented interfaces
Date Wed, 29 Nov 2017 22:36:00 GMT

    [ https://issues.apache.org/jira/browse/HBASE-19356?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16271680#comment-16271680
] 

Mike Drob commented on HBASE-19356:
-----------------------------------

What do we actually need to do here? The three types you mention are already interfaces.

When we are adding methods here we can make the new ones have default implementations, but
is there anything to change in the existing methods?

> 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], [~ankit@apache.org], and [~elserj] would
remember.
