Description

Even patched in CASSANDRA-11752, nodetool proxyhistograms/cfhistograms(2.2)/tablehistograms(3.0,3.x) still report read/write latency as flat result. That cause Cassandra metric org.apache.cassandra.metrics.ClientRequest.Read/Write.Latency.xxpercentile report incorrect pattern.

I have attached the result which I tested on cassandra 3.0.9. It indicate read latency as flat line whereas read count has a movement normally.
