1.系统环境和形相应软件版本: centos6.5 green-plum的版本是4.3.5.2

2.安装中出现的问题:
gpinitsystem -c gpinitsystem_config -h seghost
但是它一直报错:

pstop failed. (Reason='int() argument must be a string or a number,
not 'NoneType'') exiting...
20170419:15:55:11:gpinitsystem:mdw:gpadmin-[FATAL]:-Failed to stop new
Greenplum instance, check log file Script Exiting!

不知道是什么原因造成的,大神指教.

但是在gpAdminLogs目录下还有一个gpstop_20170419.log(相关内容为):
