2. Unzip and Install PIG

After Downloading the PIG, we need to Unzip the pig-0.17.0.tar.gz file.

Fig 2:- Extracting PIG Step-1

Once extracted, we would get a new file pig-0.17.0.tar.
Now, once again we need to extract this tar file.

Fig 3:- Extracting PIG Step-2

• Now we can organize our PIG installation, we can create a folder and move the final extracted file in it. For Eg. :-

Fig 4:- PIG Directory

• Please note while creating folders, DO NOT ADD SPACES IN BETWEEN THE FOLDER NAME.(it can cause issues later)

• I have placed my PIG in D: drive you can use C: or any other drive also.

3. Setting Up Environment Variables

Another important step in setting up a work environment is to set your Systems environment variable.

Go to Control Panel > System > click on the “Advanced system settings” link to edit environment variables.
Alternatively, We can Right-click on This PC icon and click on Properties and click on the “Advanced system settings” link
Or, the easiest way is to search for Environment Variable in the search bar and there you GO…😉

Fig. 6:- Advanced System Settings Screen

3.1 Setting PIG_HOME

• Open environment Variable and click on “New” in “User Variable”.

Fig. 7:- Adding Environment Variable

• On clicking “New”, we get the below screen.

Fig. 8:- Adding PIG_HOME

• Now as shown, add PIG_HOME in variable name and path of PIG in Variable Value.

• Click OK and we are half done with setting PIG_HOME.

3.2 Setting Path Variable

• The last step in setting the Environment variable is setting Path in System Variable.

Fig. 9:- Setting Path Variable

• Select Path variable in the system variables and click on “Edit”.

Fig. 10:- Adding Path

• Now we need to add these paths to Path Variable:-
  * %PIG_HOME%\bin

• Click OK and OK. & we are done with Setting Environment Variables.

Note:- If you want the path to be set for all users you need to select “New” from System Variables.

3.3 Verify the Paths

• Now we need to verify that what we have done is correct and reflecting.

• Open a NEW Command Window.

• Run following commands.

echo %PIG_HOME%

4. Verifying Setup

Congratulation..!!!!!
We are done with setting up the PIG on our System.
Now we need to check if everything works smoothly…
Open a cmd window, run the below command to test the connection and PIG.

pig -version

Upon running the command we should get the version of PIG. i.e 0.17.0 in our case.

Fig 11:- Checking PIG version

 Congrats… we have successfully installed PIG-0.17.0 on our WIndows 10. 

Don’t worry some of us can get the below error after running pig -version 

'-Xmx1000M' is not recognized as an internal or external command, operable program or batch file.

To resolve this we will need to perform the following steps:- 

1. Open the pig. cmd file in edit mode. 
   We can find the file in the bin folder. 

Fig 12:- pig.cmd file

2. Now we need to change the value of the HADOOP_BIN_PATH

Old value:-   %HADOOP_HOME%\bin
New Value:-   %HADOOP_HOME%\libexec


3. Save the file.
The next step is to verify the setup once again. So, we need to execute the 
pig -version command once again.


5. Starting PIG

Now we need to start a new Command Prompt remember to run it as 
administrator to avoid permission issues and execute the below commands

pig

Yes, it's that simple… We can see grunt> once the pig starts.

There are chances that some of us might have faced some issues… 
Don’t worry it's most likely due to some small miss or incompatible software. 
If you face any such issue please visit all the steps once again carefully and
verify for the right software versions.
