Storing field in a bag
I am trying to store field in a bag command but it fails with
store b.page into '/flume_vol/flume/input/page.dat';
store b.network into '/flume_vol/flume/input/network.dat';
B: {b: {(page: chararray,network: chararray,sysinfo:
chararray,trafficsource: chararray,search: chararray)}}
2012-09-10 10:45:54,293 [main] ERROR org.apache.pig.tools.grunt.Grunt -
ERROR 1200: <file script5_snappy.pig, line 24, column 7> mismatched input
'.' expecting INTO

Can I do this without using foreach?

You can achieve equivalent functionality by saying:
page = foreach b generate page;
store page into '/flume_vol/flume/input/page.dat';
network = foreach b generate network;
store network into '/flume_vol/flume/input/network.dat';

Hi, Mohit,
http://pig.apache.org/docs/r0.7.0/piglatin_ref2.html#STORE
I guess you can only STORE relations, not fields, etc
