> Key: PIG-1626
> URL: https://issues.apache.org/jira/browse/PIG-1626
> Project: Pig
> Issue Type: Bug
> Components: documentation
> Reporter: Olga Natkovich
> Assignee: Corinne Chandel
> Fix For: 0.8.0
>
>
> The current documentation just states: "The COUNT function ignores NULL
> values. If you want to include NULL values in the count computation, use
> COUNT_STAR. "
> The new text should be something like
> "The COUNT function follows syntax semantics and ignores nulls. What this
> means is that a tuple in the bag will not be counted if the first field in
> this tuple is NULL. If you want to include NULL values in the count
> computation, use COUNT_STAR. "
