> This is a patch to fix errors and lacks in document "Pig Latin Basics".
> # States that COGROUP groups records with a null key _from different
> relations_ separately.
> # "A map key must be a -scalar- +chararray+ "
> # Removes a statement which says that a star expression is a tuple expression
> (it seems incorrect)
> # Fixes a subject confusion of a sentence "When two bytearrays are used in
> arithmetic expressions..."
> # Updates a link to Java API documentation.
> # Fixes a tuple example: "LOAD 'data' as..." -> "A = LOAD 'data' as..."
> # "the asterisk (\*) is used to project all -tuples- +fields+ "
> # A result of COGROUP with two relations contains _three_ fields, not _two_
> # Removes an example of COGROUP INNER, which is deprecated
> # Removes a sentence which says "JOIN operator always performs an inner
> join". Actually, JOIN also perform an outer join.
> # JOIN "Performs an outer join of two -ore more- relations"
> # Replaces an example of "-Dpig.additional.jars" with a jar file on HDFS. The
> current version incorrectly shows an example of a Pig script on HDFS.
> # Fixes typos, lack of hyperlinks, inappropriate indentation, and incorrect
> chaptering.
