The thread name is not relevant in MR mode, and is redundant in your example
output above.
{code}
+ String metricName =
+ testName + "-Client-" + Thread.currentThread().getName() +
"-testRowTime";
{code}

Adding thread name in the metric name is to distinguish metrics from different
threads in no mapred mode. The the thread names in the log are added by the
setStatus automatically and i will remove one.
Thanks for your review and I will update the patch later.
