Date Mon, 13 Mar 2017 04:40:04 GMT

     [ https://issues.apache.org/jira/browse/CASSANDRA-13234?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jeff Jirsa updated CASSANDRA-13234:
-----------------------------------
    Resolution: Fixed
        Status: Resolved  (was: Ready to Commit)

Committed as [0c5faef664aa403998f59cc77c9b39861890cfa1|https://github.com/apache/cassandra/commit/0c5faef664aa403998f59cc77c9b39861890cfa1]
to trunk only (because [~iamaleksey] , it's a new feature, doesnt go into lowers).

Added changes.txt entry and fixed up the extra nits at commit time.

Thanks for the review, [~spodxx@gmail.com] !

> There is very little visibility into hint delivery in general - having histograms available
to understand how long it takes to deliver hints is useful for operators to better identify
problems.
