> In PIG-3627, we discover flatten(STRSPLIT) generate null schema. 
> Here is the sample:
> {code}
> a = load 'a' as (line:chararray);
> b = foreach a generate flatten(STRSPLIT(line)) as (i0, i1, i2);
> describe b;
> b: {i0: NULL,i1: NULL,i2: NULL}
> {code}
> PIG-3627 fixed the JsonStorage to deal with null schema. In this ticket, we will fix the null schema generation.
