[jira] [Updated] (PIG-2267) Make the name of the columns in schema optional

["Daniel Dai (Updated) (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/PIG-2267?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Daniel Dai updated PIG-2267:
----------------------------

      Resolution: Fixed
    Release Note: 
Name part of the schema is optional in as clause in load and foreach statement. For example:
a = load 'data' as (int);
a = load 'data' as ({(int,int)});
y = foreach x generate x0 as int;
y = foreach x generate x0 as {(int, int)};

Pig will generate dummy name if the name part is missing.

     [exec] 
     [exec]     -1 javac.  The applied patch generated 898 javac compiler warnings (more than the trunk's current 894 warnings).
     [exec] 
     [exec]     +1 findbugs.  The patch does not introduce any new Findbugs warnings.
     [exec] 
     [exec]     -1 release audit.  The applied patch generated 510 release audit warnings (more than the trunk's current 502 warnings).

javac warning is caused by antlr generated code. I added Apache header to all new files, so ignore release audit warning.

Patch committed to trunk. Thanks Jonathan!
