> For example this is my script:(join_jira1.pig)
> register /grid/0/dev/hadoopqa/jars/zebra.jar;
> --a1 = load '1.txt' as (a:int, b:float,c:long,d:double,e:chararray,f:bytearray,r1(f1:chararray,f2:chararray),m1:map[]);
> --a2 = load '2.txt' as (a:int, b:float,c:long,d:double,e:chararray,f:bytearray,r1(f1:chararray,f2:chararray),m1:map[]);
> --sort1 = order a1 by a parallel 6;
> --sort2 = order a2 by a parallel 5;
> --store sort1 into 'asort1' using org.apache.hadoop.zebra.pig.TableStorer('[a,b,c,d]');
> --store sort2 into 'asort2' using org.apache.hadoop.zebra.pig.TableStorer('[a,b,c,d]');
> --store sort1 into 'asort3' using org.apache.hadoop.zebra.pig.TableStorer('[a,b,c,d]');
> --store sort2 into 'asort4' using org.apache.hadoop.zebra.pig.TableStorer('[a,b,c,d]');
> joinl = LOAD 'asort1,asort2' USING org.apache.hadoop.zebra.pig.TableLoader('a,b,c,d', 'sorted');
> joinr = LOAD 'asort3,asort4' USING org.apache.hadoop.zebra.pig.TableLoader('a,b,c,d', 'sorted');
> joina = join joinl by a, joinr by a using "merge" ;
> dump joina;
