Miyakawa Taku updated PIG-3085:
-------------------------------
Description:
Errors and lacks in document "Built In Functions"
This is a patch to fix errors in document "Built In Functions".
# Heading of the result table of ROUND function is wrongly written as
??CEIL(\x)??
# "Syntax" clause of LAST_INDEX_OF function is wrongly written as
??LAST_INDEX_OF(expression)??, but the function actually takes three arguments
# "Syntax" clause of REGEX_EXTRACT_ALL function is wrongly written as
??REGEX_EXTRACT (string, regex)??
# An example of REPLACE function is terminated by a semicolon:
??REPLACE(string,'software','wiki');??, but the semicolon is not necessary in
Pig Latin syntax
# "limit" argument of STRSPLIT function is described as ??The number of times
the pattern ... is applied??. But actually, _limit-1_ is the maximum number of
times the pattern is applied, and "limit" means the maximum length of the
result tuple (if the value is positive). If the value is 0 or negative, not
limit is applied.
# An example program of TOP function does not work, because it uses
??COUNT(\*)??
# Fixes typos
## "COUNT_STAR is used -the- +to+ count ..."
## "delimit in JsonLoader or -JsonStorer- +JsonStorage+ ..."
## "using field -deliminters- +delimiters+ ..."
## "If you store -reading- +using+ delimiter "#" ..."
## "The STORE -function- +statement+ specifies that the files ..."
## "Limit" -> "limit" in a term definition of STRSPLIT function
