Hi @lwang .

Thank you for the quick response. I've solved the problem already. I found out that there are hung requests in the Ambari DB specifically on host_role_command which in charge of the Ambari Web UI operation. I remove those hung requests and resolved the problem. My cluster is now running smoothly. Thanks
