---------------------------------
Summary: Use MutableQuantiles to provide latency histograms for
various operations
Key: HDFS-3650
URL: https://issues.apache.org/jira/browse/HDFS-3650
Project: Hadoop HDFS
Issue Type: Improvement
Affects Versions: 2.0.0-alpha
Reporter: Andrew Wang
Assignee: Andrew Wang
Fix For: 2.0.1-alpha
MutableQuantiles provide accurate estimation of various percentiles for a
stream of data. Many existing metrics reported by a MutableRate would also
benefit from having these percentiles; lets add MutableQuantiles where we think
it'd be useful.
