> When loading data as a bag, if the schema specification is not correct, error
> message does not include useful information about bag.
> For example, input file as "input.txt", working script as "working.pig", non
> working as "not_working.pig" as following:
> input.txt
> {(2, 3)}
> {(4, 6)}
> {(5, 7)}
> not_working.pig
> A = LOAD 'input.txt' AS (f1:bag[T:tuple(t1, t2)]);
> describe A;
> dump A;
> working .pig
> A = LOAD 'input.txt' AS (f1:bag{T:tuple(t1, t2)});
> describe A;
> dump A;
> if run: " pig -latest -x local working.pig", we get result:
> ({(2, 3)})
> ({(4, 6)})
> ({(5, 7)})
> if run " pig -latest -x local not_working.pig", we get:
> ERROR org.apache.pig.tools.grunt.Grunt - ERROR 1000: Error during parsing.
> Encountered " "bag" "bag "" at line 1, column 29.
> Was expecting one of:
> "int" ...

> "bytearray" ...
> "int" ...
> "long" ...
> "float" ...

> "bytearray" ...
> Please include bag{} map[] tuple() in Error message for better addressing the
> error.
