Installation of Apache Pig 0.17.0 on Ubuntu 16.04.3

Step 1:  Download Pig tar file.

hduser@Soumitra-PC:~$ wget http://www-us.apache.org/dist/pig/pig-0.17.0/pig-0.17.0.tar.gz

Step 2: Extract the tar file using tar command. 

In below tar command, x means extract an archive file, z means filter an archive through gzip, f means filename of an archive file.

hduser@Soumitra-PC:~$ tar -xzf pig-0.17.0.tar.gz 

hduser@Soumitra-PC:~$ ls

Step 3: Move the extracted file to /usr/local/ directory

hduser@Soumitra-PC:~$ sudo mv /home/hduser/pig-0.17.0 /usr/local

Step 4: Edit the “~.bashrc” file to update the environment variables of Apache Pig. 

hduser@Soumitra-PC:~$ sudo gedit ~/.bashrc

Add the following at the end of the file:

#PIG VARIABLES START

export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64
export PIG_HOME=/usr/local/pig-0.17.0

export PATH=$PATH:$PIG_HOME/bin

export PIG_CLASSPATH=$HADOOP_HOME_conf

export HADOOP_USER_CLASSPATH_FIRST=true

#PIG VARIABLES END

Also, make sure that hadoop path is also set.

Run the source command to make sure the changes get updated in the ~/.bashrc file.

hduser@Soumitra-PC:~$ source ~/.bashrc

Step 5: Check pig version. 

hduser@Soumitra-PC:~$ pig -version

Step 6: Run Pig. 

The Grunt shell can be started using the following command:

hduser@Soumitra-PC:~$ pig

Grunt Shell is used to run Pig Latin scripts.

Apache Pig can run in two modes, by default it chooses MapReduce mode. We can also run in MapReduce mode by writing the below command:

hduser@Soumitra-PC:~$ pig -x mapreduce

The other mode, local, can be run as:

hduser@Soumitra-PC:~$ pig -x local
