需求描述：需要测试cdh集群的组件的性能和稳定性。
压力测试工具选型：HiBench
HiBench测试工具说明：
HiBench是一套基准测试套件，用于帮助我们评估不同的大数据框架性能指标（包括处理速度、吞吐等）的负载指标，可以评估Hadoop、Spark和流式负载等
源码下载：wget https://github.com/intel-hadoop/HiBench/archive/HiBench-7.0.zip
源码编译：命令：mvn -Dspark=2.1 -Dscala=2.11 clean package
官方文档：https://github.com/intel-hadoop/HiBench/blob/master/docs/build-hibench.md
前提条件：
1)、需要python2.x(>=2.6)
2)、需要linux bc命令，用于生成Hibench 报告，若没有，则安装：yum install bc
修改配置：
vim conf/hadoop.conf
hibench.hadoop.home：hadoop安装目录
hibench.hadoop.executable：你的bin/hadoop所在目录，一般是{HADOOP_HOME}/bin/hadoop
hibench.hadoop.configure.dir：hadoop配置文件所在目录，一般位于HADOOP_HOME}/etc/hadoop
hibench.hdfs.master：hdfs上存储Hibench数据的目录，如：hdfs://localhost:8020/user/hibench
hibench.hadoop.release：hadoop发行版提供者，支持value：apache, cdh5, hdp
