Andrew Purtell updated HBASE-8966:
----------------------------------

    Affects Version/s:     (was: 0.94.10)
                           (was: 0.98.0)
                           (was: 0.95.2)
             Assignee:     (was: Andrew Purtell)

bq. From the doc: Neither DescriptiveStatistics nor SummaryStatistics is thread-safe.

Thanks, originally I had synchronized blocks around the updates but removed them. Seems the
version of the patch I put up is missing that todo, sorry about that. 

bq. Last time, I checked DescriptiveStats, I remember being concerned about it's performance.


Yeah, so then I'm going to remove the fix versions and just leave this hanging around, because
I can see this is going to be more involved than I want to invest time in.

> LoadTestTool does not provide summary statistics after completion. Provide them. Make
them similar to YCSB summary output for post parsing convenience.
