Hi Venugopal,

The installation of Sqoop (Sqoop 1) is simple and can be done in these very simple step

  1. Ensure that the environmental variables for your hadoop installation $HADOOP_HOME. The same value should be set to a new variable $HADOOP_COMMON_HOME and $HADOOP_MAPRED_HOME.
  2. Download the zipped archive from the sqoop apache download page.
  3. Extract the archive to a location you want
  4. Create an enviromental variable $SQOOP_HOME to be the location you extracted the archive in step 2.
  5. Then add to your environmental variable PATH the values of $SQOOP_HOME/bin

Having done the above, you can be able to call the sqoop tool from comand.

An example will be checking the version of sqoop installation by running the command sqoop version.

To sqoop to import/export data from/to any relational database to/from HDFS, follow the following simple steps

  1. Search for and download the jdbc driver for the relational database you want to walk with.
  2. copy the jar to $SQOOP_HOME/lib directory. 

You can begin to use sqoop by using the appropriate sqoop cli.

Hi Venugopal,

1. Download the sqoop

2) Untar the download file
    tar -xvzf sqoop-1.4.4.bin_hadoop-1.0.0.tar.gz

3) Copy the extracted folder into sqoop location
    sudo cp -r sqoop-1.4.4.bin_hadoop-1.0.0 /usr/local/sqoop

4) Set the paths in the bash environment
    sudo vi .bashrc
    
    export PATH=$PATH:/usr/local/sqoop/bin
    export HADOOP_HOME=/usr/local/hadoop/
    export HADOOP_COMMON_HOME=/usr/local/hadoop/
    export HADOOP_MAPRED_HOME=/usr/local/hadoop/
    export HIVE_HOME=/usr/local/hive
    export HBASE_HOME=/usr/local/hbase
    export PATH=$HIVE_HOME/bin:$PATH
    
5) Update bash
    exec bash

          
6) Add permissions
        sudo chown hadoop /usr/local/sqoop
        sudo chown hadoop /usr/local/sqoop/bin
        sudo chown hadoop /usr/local/sqoop/lib
        sudo chown hadoop /usr/local/sqoop/conf
        
7) Download mysql jdbc connector(mysql webiste) and copy into /usr/local/sqoop/lib.

 

Hope this helps.

Thanks
