Subject [jira] [Commented] (HBASE-10511) Add latency percentiles on PerformanceEvaluation
Date Wed, 12 Feb 2014 22:30:20 GMT

    [ https://issues.apache.org/jira/browse/HBASE-10511?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13899690#comment-13899690

Jean-Marc Spaggiari commented on HBASE-10511:
---------------------------------------------

Not on my side. As you said, will be more readable. Or maybe chance 

LOG.info("randomRead latency log (ms): " + Arrays.toString(times));

by

LOG.trace("randomRead latency log (ms): " + Arrays.toString(times));

So we have only the most readable output that you have added, but still can get the hugly
one if required? Listing all the values might be useful to get graphs output of the results...

> The latency is reported as an array or float. It's easier to deal with percentiles :-)
