@rizalt It's hard to talk to a solution here without a lot more details (version of stack, ambari, java, etc).  That said,  some of the hits I find against this error are from 2017(many years ago).  There is a great risk to operate Ambari as it is no longer supported and available within the Cloudera ecosystem.       I would recommend you evaluate modern solutions (CDP) for the same stack of services you are familar with in Ambari. ...
