3. Validate the Installation

Use the following steps to validate your installation:

Use a terminal window on a machine where Pig is installed and execute the following commands :
```
login as $HDFS_USER
/usr/lib/hadoop/bin/hadoop dfs -copyFromLocal /etc/passwd passwd
```

Execute the following commands to produce script file /tmp/id.pig:

echo "A = load 'passwd' using PigStorage(':'); " > /tmp/id.pig
echo "B = foreach A generate \$0 as id; store B into '/tmp/id.out'; " >> /tmp/id.pig
