> /**
>  * 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}.
