在安装greenplum集群进行初始化的时候报错？不知道什么原因？

本人在安装greenplum集群进行初始化的时候报错，1个节点做master，2个节点做Segment，1个节点做Master Standy。
在进行初始化数据库的时候：
[gpadmin@iZ115m3daskZ ~]$ gpinitsystem -c /home/gpadmin/conf/gpinitsystem_config -s iZ1191gmulmZ
find: 鈥opt/greenplum/greenplum-db/./greenplum-db-4.3.9.0鈥 Too many levels of symbolic links

同样也一样的报错
不知道是什么原因？
哪位大师可以解释下？
谢谢
