A piece of data. Note 1: boolean (Tuple A is equal to tuple B if they have the same size s, and for all 0 <= i < s A[i] == B[i]), Note 2: boolean (Map A is equal to map B if A and B have the same number of entries, and for every key k1 in A with a value of v1, there is a key k2 in B with a value of v2, such that k1 == k2 and v1 == v2), *Cast as chararray (the second argument must be chararray).

If none of these pet pig names catch your eye, we have suggestions on how to brainstorm your own and pick the perfect pig name. A Pig relation is similar to a table in a relational database, where the tuples in the bag correspond to the rows in a table. These operators handle nulls differently (see examples below). You can think of a tuple as a row with one or more fields, where each field can be any data type and any field may or may not have data. The type applies to the map value only; the map key is always type chararray (see Map). The values for inputLocation and outputLocation can be passed in the params. In this case <> is used to indicate required items. You can use a built in function (see the Load/Store Functions). Note that if an explicit cast is not used an implict cast will be inserted according to Pig rules. If the schema is null, Pig treats all fields as bytearray (in the backend, Pig will determine the real type for the fields dynamically). The second field is name "A" after relation A and is type bag. I want good names and nothing like; bacon, piggers, pinky, babe, wilbur, or any of those obvious names. Outer joins will only work provided the relations which need to produce nulls (in the case of non-matching keys) have schemas. Pig will pick up all JARs that match the glob. They make wonderful pets. Three guinea pigs are even more fun than two. It’s no secret that pigs can be adorably cute, but did you know they are also pretty funny? Translates directly to a Maven groupId or an Ivy Organization. If you retrieve relation X (DUMP X;) the data is guaranteed to be in the order you specified (descending). Examples include "Pig Newton," "Pigson Ablanket," and "New Guinea". Use the SPLIT operator to partition the contents of a relation into two or more relations based on some expression. In this example data is stored using PigStorage and the asterisk character (*) as the field delimiter.
