Subject [jira] [Commented] (HBASE-17312) [JDK8] Use default method for Observer Coprocessors
Date Thu, 16 Feb 2017 22:43:41 GMT

    [ https://issues.apache.org/jira/browse/HBASE-17312?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15870809#comment-15870809

Andrew Purtell commented on HBASE-17312:

No discussion needed. My answer is based on a lack of discussion actually. Look at what's
supported on master. Note the lack of discussion about 2.0. :-) 

Sure, Phoenix won't be on 1.x forever. When they move to 2.x there will be a lot of work needed
regardless, as you point out [~enis]

> Use default method in MasterObserver, RegionObserver, RegionServerObserver and WALObserver.
And mark the BaseRegionObserver, BaseMasterAndRegionObserver, BaseRegionServerObserver and
BaseWALObserver. User can implement the interface directly and will not break compatibility
when add new default methods.
