This is regression for dotNext.
a = load '/user/user1/pig/tests/data/singlefile/studenttab10k';
b = load '/user/user1/pig/tests/data/singlefile/votertab10k';
c = order a by $0;
d = order b by $0;
store c into
'/user/user1/pig/out/user1.1322779146/dotNext_MergeJoin_1.out.intermediate1';
store d into
