Hive Installation

A. Pre-Requisite: 

Hadoop

B. Hive Installation steps:

2. Extract Hive : tar -xzf hive-0.10.0-bin.tar.gz (it will extract to a folder hive-0.10.0-bin)

3. sudo mv hive-0.10.0-bin/ hive

4. sudo mv hive/ /usr/hadoop/.

5. cd /usr/hadoop

6. sudo chown -R hduser:hadoop hive/

7. Set below Env variables (under hduser).
export HIVE_HOME=/usr/hadoop/hive
export PATH=$HIVE_HOME/bin:$PATH
(Make sure hadoop is started. To start Hadoop, ssh localhost; start-all.sh)
hive 
8. hive

it will give you hive prompt. So that you can start accessing default DB or create new DB :)

Note: hduser is the user under which I have installed hadoop & hive. In your case it may be different

********** End of Hive Installation - Enjoy SQL based HDFS tool ***************************
