Executing SQL Script file in Hive

The Hive scripts are used to collectively execute a series of SQL Commands. In other words, multiple SQL statements can be grouped and executed all at once. This helps to reduce the time and effort expended in manually drafting and executing any command. Hive supports scripting from versions of Hive 0.10.0 and beyond.

Ok, let’s see how to execute SQL files in Apache Hive.
1) Create a .sql file with set of SQL commands.
2) Save it in the local directory as shown below


3) Open HDFS terminal and enter the below command.
Hive -f /home/cloudera/sample.sql

The default location of the files is “/home/cloudera” if you are using Cloudera’s QuickStart VM. Providing full path of the file is optional if the file is already in the home (default) directory. You can use –

Hive -f sample.sql
