Hive cli asking username and password

[#1]

I have a new cluster with HDP-3.0.1.0 without kerberos or any security. But when I use hive cli it is asking username and password to enter:

[root@ip-XXX-XX-XX-XXX ~]# hive
SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/usr/hdp/3.0.1.0-187/hive/lib/log4j-slf4j-impl-2.10.0.jar!/org/slf4j/impl/StaticLoggerBinder.class]

It should directly go inside hive cli. Could you please let me know what property I need to change.

[#2]

hive cli is deprecated in HDP3.x version and  executing it would take you to the same process of beeline. A new variable is set in script USE_BEELINE_FOR_HIVE_CLI=true which will make hive cli  session to go use beeline. 

It is no longer recommended to use hive cli. Please use beeline session in HDP 3.x

If you understand the risks of using hive CLI and still want to use, then change the script to set USE_BEELINE_FOR_HIVE_CLI=false which we don't recommend, but this is one way of making hive cli to work in HDP 3.

Without authentication configured on hive, you can give any name and password at beeline prompt and beeline will allow the access. Even blank username/password is accepted, but this would set user name as 'anonymous' .

Either way HIVE or Beeline you MUST provide username /password to authenticate to be able to execute any SQL statement against the DB. See below examples

If you have ranger plugin enable for hive then you will have authorization centrally handles by Ranger.
