How to Install Hive on Ubuntu

Below is a step by step process on how to install Hive in Ubuntu:

Step 1) Download and Install Hive on Ubuntu

For downloading Hive stable setup refer Apache URL as mentioned below

http://www.apache.org/dyn/closer.cgi/hive/. Go to the URL and select the apache mirror download link.

Select the Latest version of Hive setup. (In my current case it is hive – 3.1.2)

Click on the bin file and downloading will start.

Step 2) Extract the tar file

Go to the downloaded Tar file location ->extract the tar file by using the following command to install Hive Ubuntu on your system

tar –xvf  apache-hive-3.1.2-bin.tar.gz

Step 3) Place different configuration properties in Apache Hive

In this step, we are going to do two things

Placing Hive Home path in bashrc file
Placing Hadoop Home path location in hive-config.sh

Mention Hive Pathin ~/.bashrc

Open the bashrc file as shown in above screenshot
Mention Hive home path i.e., HIVE_HOME path in bashrc file and export it as shown in below

Code to be placed in bashrc

export HIVE_HOME="/home/guru99hive/apache-hive-1.2.0-bin"
export PATH=$PATH:$HIVE_HOME/bin

Exporting Hadoop path in Hive-config.sh (To communicate with the Hadoop eco system we are defining Hadoop Home path in hive config field)Open the hive-config.sh as shown in below

Mention the HADOOP_HOME Path  in hive-config.sh file as shown in below  ( HADOOP_HOME Path)

Step 4) Create Hive directories in Hadoop

To communicate with Hadoop, we need to create directories in Hadoop as shown below.

Giving root permissions to create Hive folders in Hadoop. If it doesn’t throw any error message, then it means that Hadoop has successfully given permissions to Hive folders.

Step 5) Enter into Hive shell

Getting into Hive shell by entering ‘. /hive’ command as shown in below.

Hive shell commands

Here we are going to create sample table using Hive shell command “create” with column names.

Sample Code for creating data base in Hive

From the above screen shot we can observe the following:

Creation of Sample Table with column names in Hive

Here the table name is “product” with three column names product, pname, and price
The three column names denoted by their respective data type
All fields are terminated by coma ‘, ‘

Displaying Hive Table information

Using “describe” command we can able to see the table information present in Hive
Here it is displaying column names with their respective data types present in table schema
At the end, it will display time to perform this command and number of rows it fetched

Sample Code for creating data base in Hive (For self check )

1) Create table product(product int, pname string, price float)

Row format delimited
Fields terminated by ',';

2)describe product:
