-------------------------------------------------------------
Key: CASSANDRA-2123
URL: https://issues.apache.org/jira/browse/CASSANDRA-2123
Project: Cassandra
Issue Type: Bug
Components: Tools
Affects Versions: 0.7.1
Reporter: Chris Burroughs
Priority: Minor
As first reported Oleg Proudnikov in the thread http://www.mail-archive.com/user@cassandra.apache.org/msg09607.html the columns for read and write latency are reversed in the output of cfhistograms. The Mbean values are correct.
