[jira] [Updated] (PIG-3085) Errors and lacks in document "Built In
Functions"
[ https://issues.apache.org/jira/browse/PIG-3085?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
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
