In rpm spec:
```
# remove RESOURCE_MANAGEMENT_DIR if it's a directory
if [ -d "$RESOURCE_MANAGEMENT_DIR" ]; then # resource_management dir exists
if [ ! -L "$RESOURCE_MANAGEMENT_DIR" ]; then # resource_management dir is
not link
rm -rf "$RESOURCE_MANAGEMENT_DIR"
fi
fi
```
These links will be removed when install rpm installation.
And no issues occurred by directly using `rpm -i` :
```
rpm -ivh ambari-server-2.7.5.0-1.el7.noarch.rpm
rpm -qa | grep 'ambari'
rpm -e ambari-server-2.7.5.0-1.el7.noarch
```
