HIVE Installation And MySql configuration

As we all know HIVE is based on Hadoop and works on MapReduce and HDFS.

Step 1) Go to and download apache-hive-1.2.1-bin.tar.gz

Step 2) Go to downloaded directory and extract

tar -xvf apache-hive-1.2.2-bin.tar.gz

Step 3) Different Configuration properties to be placed in Hive.

In this step, we are going to do two things

  1. Placing Hive Home path in bashrc file
  2. Placing Hadoop Home path location in
  • 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/radhe/apache-hive-1.2.0-bin”

export PATH=$PATH:$HIVE_HOME/bin

Step 4: Download and install derby/MySQL Database

Why to Use MySQL in Hive as Meta store:

  • By Default, Hive comes with derby database as metastore.
  • Derby database can support only single active user at a time
  • Derby is not recommended in production environment

So the solution here is

  • Use MYSQL as Meta storage at backend to connect multiple users with Hive at a time
  • MYSQL is Best choice for the standalone metastore.

Step 5) Download MySQL and install. Once installation done, Create MySQL user

To install the MySQL connector on a Debian/Ubuntu system:

Install mysql-connector-java and symbolically link the file into the /usr/lib/hive/lib/ directory.

$ sudo apt-get install libmysql-java
$ ln -s /usr/share/java/libmysql-java.jar /usr/lib/hive/lib/libmysql-java.jar

Execute the commands as shown below,

mysql> CREATE USER ‘hiveuser’@’%’ IDENTIFIED BY ‘hivepassword’;

mysql> GRANT all on *.* to ‘hiveuser’@localhost identified by ‘hivepassword’;

mysql> flush privileges;

Step 6) Configuring hive-site.xml

  • After Step 5 assign username and password to MySQL database and given privileges.
  • Here we will configure some properties in Hive to get a connection with MySQL database.

Place this code in hive-site.xml


		<description>metadata is stored in a MySQL server</description>
		<description>MySQL JDBC driver class</description>
		<description>user name for connecting to mysql server</description>
		<description>password for connecting to mysql server</description>

Step 7) Create table using hive command
hive> create table products(id int, name string);
Step 8) Go to MySql prompt and execute following command
mysql> use metastore ;//select database which is hive using
mysql>show tables;
Tables in metastore
