Subject [jira] [Commented] (HBASE-10791) Add integration test to demonstrate performance improvement
Date Sat, 22 Mar 2014 02:22:47 GMT

    [ https://issues.apache.org/jira/browse/HBASE-10791?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13943847#comment-13943847

Nick Dimiduk commented on HBASE-10791:
--------------------------------------

48 mins vs 14 is too much of a difference. I wonder if a security token expired in the middle
of the run. I don't have debug entries in my MR logs, but running in local mode reveals lots
of... extras. I think the test does what's intended, need to run on a non-secured cluster
to eliminate a variable here.

> It would be good to demonstrate that use of region replicas reduces read latency. PerformanceEvaluation
can be used manually for this purpose, but it's not able to use ChaosMonkey. An integration
test can set up the monkey actions and automate execution.
