-------------------------
Description:
step 1:

# stop all the service on the host,
# use api delete host
step 2:
# prepare a host, install agent
# add a node to the cluster use api and install service
# regenerate_keytab
# ambari hang at preparing operations/hostname/preparing operations
it is because step1.3 cannot completely clear all this host kerberos
idetities in both database(mysql ) and kdc(kdc.admin)
in mysql there are 3 table kkp_mapping_service, kerberos_keytab_principal,
kerberos_keytab,kerberos_principal, host related kerberos identities in these
tables must be deleted completely,
in kdc , use kadmin.local "listprincs *hostname*"
