> /**
> * Build a bloom filter for use later in Bloom. This UDF is intended to run
> * in a group all job. For example:
> * define bb BuildBloom('jenkins', '100', '0.1');
> * A = load 'foo' as (x, y);
> * B = group A all;
> * C = foreach B generate BuildBloom(A.x);
> * store C into 'mybloom';
> * The bloom filter can be on multiple keys by passing more than one field
> * (or the entire bag) to BuildBloom.
> * The resulting file can then be used in a Bloom filter as:
> * define bloom Bloom(mybloom);
> * A = load 'foo' as (x, y);
> * B = load 'bar' as (z);
> * C = filter B by Bloom(z);
> * D = join C by z, A by x;
> * It uses {@link org.apache.hadoop.util.bloom.BloomFilter}.
