    Description

      when two kerberos cluster establish cross realm trust, we should set up hadoop.security.auth_to_local parameter in both clusters, and then restart cluster。restart namenode is very challenge thing for large cluster, so we can add admin command to refresh auth to local rules without restart cluster.
