Nicolas Liochon commented on HBASE-10791:
-----------------------------------------
One nit: for the settings, it would be better to use the public String (ex:
RpcClient.ALLOWS_INTERRUPTS) than hardcoding the property name.
The results are different from what I was seeing on a real cluster a few months
ago:
bin/hbase org.apache.hadoop.hbase.PerformanceEvaluation --replicas=1
--rows=10000 --nomapred randomRead 1
replicas = 1: Min: 1767ms Max: 1767ms Avg: 1767ms
replicas = 2: Min: 103804ms Max: 103804ms Avg: 103804ms
> Add integration test to demonstrate performance improvement

> Project: HBase
> Issue Type: Sub-task
> Components: Performance, test
> Affects Versions: hbase-10070
> Reporter: Nick Dimiduk
> Assignee: Nick Dimiduk
> Attachments: HBASE-10791.00.patch, HBASE-10791.01.patch,
> HBASE-10791.02.patch, HBASE-10791.03.patch, HBASE-10791.04.patch,
> HBASE-10791.05.patch, IntegrationTestRegionReplicaPerf.out
>
>
> 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.
