Just share the solution to everyone here.

-----------

I have two clusters (prod and dev) all have the same problem

env:

Centos6.6 minamal

jdk1.7

CDH&CM 5.4.3

• In the HUE main page

It's shown 

Potential misconfiguration detected. Fix and restart Hue.

Hive Editor    The application won't work without a running HiveServer2. 

• In HiveEditor page

the database list could not be shown(always loading...)

I executed a simple sql and got an error "Could not start SASL: Error in sasl_client_start......."

• the solution
