Subject [jira] [Updated] (PIG-3085) Errors and lacks in document "Built In Functions"
Date Sun, 09 Dec 2012 10:07:21 GMT

     [ https://issues.apache.org/jira/browse/PIG-3085?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Miyakawa Taku updated PIG-3085:
-------------------------------

    Description: 
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(\*\)??
# Updates links to pages in the Java API Reference
# 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
