Fix Version/s: 2.1.3
> Switch cfhistograms from using yammer metrics in 2.1
> ----------------------------------------------------

> Project: Cassandra
> Issue Type: Improvement

>
>
> cfhistograms was changed to use the yammer histograms CASSANDRA-5871. Until
> CASSANDRA-5657's change to metrics we shouldn't represent the yammer
> histogram for latency metrics. Yammer's histogram is based on assumption of
> a normal distribution and is bad at representing the tail percentiles with
> skewed distributions. So revert the change just in the 2.1 branch but leave
> it for 3.0.
