Pig - exception on simple load

I just started learning pig and trying to do something with it, so I enter the pig console and simply type a = load 'sample_data.csv'; ( I have a file named sample_data.csv). I received the following exception:

Pig Stack Trace

ERROR 2998: Unhandled internal error. name

================================================================================

The content of sample_data.csv is:

1, John, Smith
2, Jane, Doe
3, George, Washington
4, Ben, Franklin

I have also set the $PIG_HOME variable to the home folder of the pig directory.

I am also aware of the similar question that's been raised before. here

However, even if I set my $PIG_CLASSPATH variable as instructed, and echoed the $PIG_CLASSPATH to make sure that it is set correctly, I still get the same error.

After scratching my head for 24 hours. I finally figured it out with the help of my colleage.

It was becuase of Hive. For some reason when both Pig and Hive are set on the same machine, this tends to happen. So all I needed to do is 

export HIVE_HOME=
