Hello @npr20202 ,

 

Could you specify from which log do you see this error. And what jobs are failing because of this error?

What is the CM version and CDH version?

Please ensure that KMS, Keytrustee Server, and keyHSM are in good health.

Please check KTS log, if the error is there please share the full error stack.

 

Thanks,

Will
