huangsheng commented on KYLIN-5597:
-----------------------------------

h1. Fix Design:

change
{code:java}
if [[ "${kerberosEnabled}" == "false" || -f ${BYPASS} ]] {code}
to
{code:java}
if [[ "${kerberosEnabled}" != "true" || -f ${BYPASS} ]]{code}
 

This ensures that the jar is not replaced when kerberosEnabled is empty

> When the /etc/hosts file of the KE node does not configure the IP 
> corresponding to the cluster domain name in the hadoop conf configuration 
> file, KE will fail to start
