一：未安装或未指定java环境变量
[root@ecs-1ae9-0001 Packages]# ./runBenchmark.sh props.dm

配置JAVA 环境变量
export JAVA_HOME=/dm/dmdbms/dmdbms/jdk
export PATH=$JAVA_HOME/bin:$PATH
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
二：测试程序和python版本不一致：
再次测试报python问题，怀疑是版本兼容问题。

[root@ecs-1ae9-0001 ~]# python3 -V
–Python 3.6.8
配置安装本地yum源
[root@ecs-1ae9-0001 Packages]#mkdir /media
[root@ecs-1ae9-0001 Packages]# ls -l /etc/yum.repos.d/
UnionTechOS-aarch64.repo UnionTechOS-everything-aarch64.repo UnionTechOS-modular-aarch64.repo UnionTechOS-update-aarch64.repo
[root@ecs-1ae9-0001 yum.repos.d]# mkdir bak
[root@ecs-1ae9-0001 yum.repos.d]# mv UnionTechOS-everything-aarch64.repo UnionTechOS-modular-aarch64.repo UnionTechOS-update-aarch64.repo bak/
[root@ecs-1ae9-0001 bak]# ls
UnionTechOS-everything-aarch64.repo UnionTechOS-modular-aarch64.repo UnionTechOS-update-aarch64.repo
[root@ecs-1ae9-0001 Packages]#
vi /etc/yum.repos.d/UnionTechOS-aarch64.repo

[root@ecs-1ae9-0001 Packages]# yum repolist
[root@ecs-1ae9-0001 Packages]# yum install ptyhon2*
