Subject [jira] Commented: (PIG-1238) Dump does not respect the schema
Date Fri, 19 Mar 2010 17:58:27 GMT

    [ https://issues.apache.org/jira/browse/PIG-1238?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12847474#action_12847474

Richard Ding commented on PIG-1238:
-----------------------------------

Hi Ankur,

I run following script

{code}
A = LOAD '1.txt' USING PigStorage();
B = FOREACH A GENERATE ['a'#'12'] as b:map[], ['b'#['c'#'12']] as mapFields;
C = FOREACH B GENERATE(CHARARRAY) mapFields#'b'#'c' AS f1, RANDOM() AS f2;
D = ORDER C BY f2 PARALLEL 10;
E = LIMIT D 20;
F = FOREACH E GENERATE f1;
dump F;
{code}

and it gets the correct result. Can you sync again with the trunk and let me know if the problem
still exists?
