hbase自带的测试工具PerformanceEvaluation

[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]

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]
