AvroStorage
Pig UDF for reading and writing Avro data.

Base
base class for math udfs

BigDecimalWrapper
Max and min seeds cannot be defined to BigDecimal as the value could go as large as The computer allows.

BigIntegerWrapper
Max and min seeds cannot be defined to BigInteger as the value could go as large as The computer allows.

BuildBloomBase
A Base class for BuildBloom and its Algebraic implementations.

DoubleBase
base class for math udfs that return Double value

DoubleSum
This method should never be used directly, use SUM.

GenericInvoker
The generic Invoker class does all the common grunt work of setting up an invoker.

LongSum
This method should never be used directly, use SUM.

Nondeterministic
A non-deterministic UDF is one that can produce different results when invoked on the same input.

OutputSchema
An EvalFunc can annotated with an OutputSchema to tell Pig what the expected output is.

PigStorage
A load function that parses a line of input into fields using a character delimiter.

INDEXOF
INDEXOF implements eval function to search for a string Example: A = load 'mydata' as (name); B = foreach A generate INDEXOF(name, ",");

LAST_INDEX_OF
string.INSTR implements eval function to search for the last occurrence of a string Returns null on error Example: A = load 'mydata' as (name); B = foreach A generate LASTINDEXOF(name, ",");

LCFIRST
lower-case the first character of a string

LOWER
LOWER implements eval function to convert a string to lower case Example: A = load 'mydata' as (name); B = foreach A generate LOWER(name);

REPLACE
REPLACE implements eval function to replace part of a string.

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().

SUBSTRING
SUBSTRING implements eval function to get a part of a string.

TRIM
Returns a string, with leading and trailing whitespace omitted.

UCFIRST
upper-case the first character of a string

JsonMetadata
Reads and Writes metadata using JSON in metafiles next to the data.

PigStorage
A load function that parses a line of input into fields using a character delimiter.
