Handling Process
There are two ways to resolve this problem.
1. Rebuild the trust relationship. Then continue the installation.
2. Cancel this task, and uninstall the services. Create a new task.
Root Cause
According to the install logs, we can find that error occurred when running the trust relationship script. So we suspect that trust relationship is not established which caused the two-node cluster communication abnormal. Then we checked the configuration and found that the Password of root was wrong. 
Suggestions
None.
