Sample script:
a = load '/user/pig/tests/data/singlefile/studenttab10k';
b = order a by $0;
store b into '/user/pig/out/praveenr-1411383735-nightly.conf/CollectedGroup_1.out.intermediate';
exec;
register ./lib/java/testudf.jar;
c = load '/user/pig/out/praveenr-1411383735-nightly.conf/CollectedGroup_1.out.intermediate' using org.apache.pig.test.udf.storefunc.SimpleCollectableLoader();
d = group c by $0 using 'collected';
e = foreach d generate group, COUNT(c);
store e into '/user/pig/out/praveenr-1411383735-nightly.conf/CollectedGroup_1.out';
