Cause
The MR service check was incorrectly calling `cached_kinit_executor` which is used for internally testing keytab files in service status checks. This found an issue where the user executing the check was not able to create the temporary ticket cache due to ACLs on the relevant directory and created file - created as the user executing ambari-agent, not the specified user.
Solution
Ensured the user specified in `cached_kinit_executor` owns the temporary ticket cache and correctly kinit-ed in the Map Reduce service check function.
