Andrew Purtell updated HBASE-8966:
----------------------------------
Attachment: 8966-0.94.patch
8966.patch
Learned about DescriptiveStatistics in commons-math thanks to
IntegrationTestMTTR, here's a trivial patch that uses it to provide YCSB-like
summary statistics after a LoadTestTool run. They look like:
{noformat}
[OVERALL], success, true
[OVERALL], runtime (ms), 51125
[OVERALL], throughput (ops/sec), 5752
[R], operations, 187787
[R], average latency (ms), 2.525920324622255
[R], min latency (ms), 0.0
[R], max latency (ms), 428.0
[R], 90% latency (ms), 4.0
[R], 95% latency (ms), 6.0
[R], 99% latency (ms), 16.0
[R], 99.9% latency (ms), 40.0
[W], operations, 105607
[W], average latency (ms), 4.751588436374124
[W], min latency (ms), 0.0
[W], max latency (ms), 468.0
[W], 90% latency (ms), 7.0
[W], 95% latency (ms), 12.0
[W], 99% latency (ms), 25.0
[W], 99.9% latency (ms), 48.0
