Answer 1

You have not provided spaces between alias name and command.
Pig expects atleast on space before or after '=' operator.
Change this line :
salaries=load 'salaries' using PigStorage(',') as (gender:chararray,details:bag{b(age:int,salary:double,zip:long)});
TO
salaries = load 'salaries' using PigStorage(',') as (gender:chararray,details:bag{b(age:int,salary:double,zip:long)});
