本文介绍HBase性能评估工具的使用方法，包括随机读写、顺序读写及全扫描等测试命令。用户可通过指定参数调整客户端数量进行性能测试。

[stack@aa0-000-12 ~]$ ./hadoop-trunk/src/contrib/hbase/bin/hbase org.apache.hadoop.hbase.PerformanceEvaluation
Usage: java org.apache.hadoop.hbase.PerformanceEvaluation[--master=host

ort] [--miniCluster] <command> <nclients>

Options:
master       Specify host and port of HBase cluster master. If not present,
               address is read from configuration
miniCluster    Run the test on an HBaseMiniCluster

Command:
randomRead    Run random read test
randomReadMem Run random read test where table is in memory
randomWrite    Run random write test
sequentialRead  Run sequential read test
sequentialWrite Run sequential write test
scan          Run scan test

Args:
nclients       Integer. Required. Total number of clients (and HRegionServers)
               running: 1 <= value <= 500
Examples:
To run a single evaluation client:
$ bin/hbase org.apache.hadoop.hbase.PerformanceEvaluation sequentialWrite 1

可以看到可以测试随机读，随机写，顺序读，顺序写，全扫描等操作，操作也简单，command后面再加一个整数值（HRegionServers的数目），范围[1,500]
