stack updated HBASE-19494:
--------------------------
Release Note:
Adds means of adding very basic filter on the sink side of replication. We
already have a means of installing filter source-side, which is better place to
filter edits before they are shipped over the network, but this facility is
needed by hbase-indexer.
Set hbase.replication.sink.walentrysinkfilter with a no-param Constructor
implementation. See test in patch for example.
> Create simple WALKey filter that can be plugged in on the Replication Sink

> hbase-indexer used to look at WALKeys on the sink to see if their time of
> creation was before the time at which the replication stream was enabled.
> In the parent redo, there is no means for doing this anymore (because WALKey
> used to be Private and because to get at the WALKey in the Sink, you had to
> override all of the Replication which meant importing a million Private
> objects...).
> This issue is about adding a simple filter to Replication on the sink-side
> that just takes a WALKey (now InterfaceAudience LimitedPrivate and recently
> made read-only).
> Assigned myself. Need to do this so hbase-indexer can move to hbase2.
