question CDP changing NameNode and role in Support Questions https://community.cloudera.com/t5/Support-Questions/CDP-changing-NameNode-and-role/m-p/334422#M231758 Hello Team, I am new to CDP. I need to change the NameNode to a different host and also need to change the Balancer to a different host and CREATE a journal node and change  role of various other hosts.  I created "HOST TEMPLATES" in accordance to my requirement and "STOPPED THE ROLES". Now, while i am trying to import the "Host Template", I get the below error. Any help is appreciated. "The maximum number of instances (1) of role type JOBHISTORY has been reached." The JOBJHISTORY refers to the Yarn JOBHISTORY. This was hosted on another node. But I have stopped the roles on that host. Yet I receive the same error.   Mon, 24 Jan 2022 05:42:16 GMT CDPTester 2022-01-24T05:42:16Z
