             Summary: [JDK8] Replace use of high-scale-lib counters with intrinsic facilities
                 Key: HBASE-7612
                 URL: https://issues.apache.org/jira/browse/HBASE-7612
             Project: HBase
          Issue Type: Sub-task
            Reporter: Andrew Purtell
            Priority: Trivial


JEP155 introduces a few new classes (DoubleAccumulator, DoubleAdder, LongAccumulator, LongAdder)
that "internally employ contention-reduction techniques that provide huge throughput improvements
as compared to Atomic variables". There are applications of these where we are currently using
Cliff Click's high-scale-lib and for metrics.
