Installing Hive

Installing Hive

Hi Guys Today we will learn how to install Hive. It is very easy and needs only few steps.

before you start installing hive, you should have already installed hadoop. If not please check out hadoop installation post.

Steps to install Hive.

1. Download Hive from Hive 0.11.0. If you want to install other version of Hive, check its comparability with hadoop version that you have already installed. In my case i am using hadoop 1.0.3

2. Go to downloads folder, right click and extract hive-0.11.0.tar.gz.

3. Copy the extracted jar into /home/hduser/hive.

4. Edit /etc/bash.bashrc and export HADOOP_HOME if not set.

       on Lubuntu

              sudo leafpad /etc/bash.bashrc

       on ubuntu

              sudo gedit /etc/bash.bashrc

        for people new to linux, leafpad and gedit are two editors to edit text files similar to notepad in windows.

5. Insert following statement in file.

        

     export HADOOP_HOME=/home/hduser/hadoop

     export HIVE_HOME= /home/hduser/hive

     export PATH=$PATH:$HADOOP_HOME/bin

     export PATH=$PATH:$HIVE_HOME/bin

6. Save the file and close it. Now close the terminal and reopen it.

7. Type hive and then enter. if your installation is right , you will log into hive shell. 

Now you can run hive queries on this shell. This installation considers embedded meta-store of hive(on derby database). In coming posts we will learn how to install hive in distributed mode.
