What Can I Do If the System Displays a Message Indicating that the Current User Does Not Exist on Manager When I Submit a Job?

Analysis: If IAM synchronization is not performed when a job is submitted to a cluster in security mode, the error message "The current user does not exist on MRS Manager. Grant the user sufficient permissions on IAM and then perform IAM user synchronization on the Dashboard tab page." is displayed.

Solution: Before you submit the job, go to the Dashboard page, and click Synchronize on the right side of IAM User Sync.
