> Pig script runs half way after which it reports syntax error

> I have a Pig script which is structured in the following way
> {code}
> register cp.jar
> dataset = load '/data/dataset/' using PigStorage('\u0001') as (col1, col2,
> col3, col4, col5);
> filtered_dataset = filter dataset by (col1 == 1);
> proj_filtered_dataset = foreach filtered_dataset generate col2, col3;
> rmf $output1;
> store proj_filtered_dataset into '$output1' using PigStorage();
> second_stream = foreach filtered_dataset generate col2, col4, col5;
> group_second_stream = group second_stream by col4;
> output2 = foreach group_second_stream {
> a = second_stream.col2
> b = distinct second_stream.col5;
> c = order b by $0;
> generate 1 as key, group as keyword, MYUDF(c, 100) as finalcalc;
> }
> rmf $output2;
> --syntax error here
> store output2 to '$output2' using PigStorage();
> {code}
> I run this script using the Multi-query option, it runs successfully till the
> first store but later fails with a syntax error.
> The usage of HDFS option, "rmf" causes the first store to execute.
> The only option the I have is to run an explain before running his script
> grunt> explain -script myscript.pig -out explain.out
> or moving the rmf statements to the top of the script
> Here are some questions:
> a) Can we have an option to do something like "checkscript" instead of
> explain to get the same syntax error? In this way I can ensure that I do not
> run for 3-4 hours before encountering a syntax error
> b) Can pig not figure out a way to re-order the rmf statements since all the
> store directories are variables
> Thanks
