service account delete and recreation question

Hello,

We setup HDP 2.6 cluster and working fine, but service accounts were created using ambari script automatically, but our security team wants to create using their script for to keep proper UID and GID. Can we simply delete and create them ? Is there any issue?

1. Shutdown the cluster

2. Delete the accounts and create the userIDs by security team.

From my understanding, it is going to remove the id from /etc/password and /etc/shadow and will recreate.

Any issues?
