无法启动greenplum - gpstart失败

我试图更新到我的greenplum机器上的最新Java，并将路径变量更改为最新的java文件夹。无法启动greenplum - gpstart失败

从那时起，我一直无法启动greenplumdb。每当我运行gpstart命令..我碰到下面的错误

gpstart failed. (Reason ='[Errno -2] name or service not known') exiting...

，如果我有一丝开始即gpstart -v ..我得到下面的输出

Traceback (most recent call last):

我不确定发生了什么，也没有在网上找到任何东西。即使是日志文件不具有许多有用的信息

这里有一些从日志文件
