Connecting to Hive using Beeline

Question

I am trying to connect to hive installed in my machine through Beeline client. when I give the \'beeline\' command & connect to Hive, the client is asking for user name

Answer 1

Accessing HIVE via Beeline:

Starting beeline client

beeline --incremental=true

Note: The command line option “—incremental=true” is optional, but will extend the amount of time that you can remain idle and not have your connection dropped.

Connecting to hive2 server

!connect jdbc:hive2://silver-server-
hive.app.google.com:10000/default

Note: You will be prompted for your username & password. USE user name and Password

beeline> !connect jdbc:hive2:// silver-server-hive.app.google.com:10000/default
scan complete in 3ms
Connecting to jdbc:hive2:// silver-server-hive.app.google.com:10000/default
Enter username for jdbc:hive2:// silver-server-hive.app.google.com:10000/default:suman
Enter password for jdbc:hive2:// silver-server-hive.app.google.com:10000/default: *********

Setting Your Queue (if any)

set mapred.job.queue.name=; 

Note: You need to set a queue in order to run queries.

Setting Your Database

USE google_map_data;

Note: You should be in a database when executing queries.

Reconnecting an inactive session

!reconnect jdbc:hive2:// silver-server-hive.app.google.com:10000/default; 

Quitting beeline client

!quit

Notes:

• Loading beeline, the URL and providing your username & password in one command:

beeline -u jdbc:hive2:// silver-server-hive.app.google.com:10000\ 
-n  -p  --incremental=true**
