MonitoredUDF Describes how the execution of a UDF should be monitored and what to do if it times out.
REGEX_EXTRACT
Syntax:
String RegexExtract(String expression String regex int match_index).
Input:
expression-source string.
regex-regular expression.
match_index-index of the group to extract.
Output:
extracted group if fail return null.
REGEX_EXTRACT_ALL
Syntax:
String RegexExtractAll(String expression String regex).
Input:
expression-source string.
regex-regular expression.
Output:
A tuple of matched strings.

SQRT SQRT implements a binding to the Java function Math.sqrt(double) Given a single data atom it Returns the square root of the argument.
STRSPLIT Wrapper around Java's String.split
input tuple: first column is assumed to have a string to split;
the optional second column is assumed to have the delimiter or regex to split on;
if not provided it's assumed to be '\s' (space)
the optional third column may provide a limit to the number of results.
If limit is not provided 0 is assumed as per Java's split().

TOBAG This class takes a list of items and puts them into a bag T = foreach U generate TOBAG($0 $1 $2); It's like saying this: T = foreach U generate {($0) ($1) ($2)} Output schema: The output schema for this udf depends on the schema of its arguments.
TOP Top UDF accepts a bag of tuples and returns top-n tuples depending upon the tuple field value of type long.
TOP.Final  
TOP.Initial
