Description

See comments toward the tail of HBASE-9393.

The change in HBASE-9393 adds dependency on CanUnbuffer interface which is currently marked @InterfaceAudience.Private

To facilitate downstream projects such as HBase in using this interface, CanUnbuffer interface should be annotated @LimitedPrivate({"HBase", "HDFS"}).
