> If a semi-colon is included in a comment that splits a GENERATE statement, Pig fails with either this error:
> ERROR 1200: <line 0, column -1>  Syntax error, unexpected symbol at or near 'null'
> or just:
> ERROR 1200: null
> This error does not happen if the comment does not split a statement.  I did not test this with non-GENERATE statements.
> This happens both in grunt and when running a pig script from a file, though it is primarily an issue with the file.
> Grunt example:
> grunt> m = LOAD '/user/suryasev/fips2.txt' USING PigStorage('\t');
> grunt> n = FOREACH m GENERATE $4 as first_item, $5 as second_item;
> grunt> describe n;
> n: {first_item: bytearray,second_item: bytearray}
> grunt> k = FOREACH n GENERATE first_item, --some comment;         
> 2013-02-22 00:19:29,974 [main] ERROR org.apache.pig.tools.grunt.Grunt - ERROR 1200: <line 0, column -1>  Syntax error, unexpected symbol at or near 'null'
