   gentle ping @turboFei 
   In the cluster mode, this merge has caused a new issue in our environment. 
   After the executor mounts the Hadoop conf file and tries to retrieve user 
information during startup, it fails to start because the conf file contains 
Kerberos authentication configuration, but the executor does not mount 
krb5.conf. Have you tested this scenario?
