Subject [jira] Resolved: (PIG-423) type information is lost in nested expressions
Date Tue, 09 Sep 2008 20:17:44 GMT

     [ https://issues.apache.org/jira/browse/PIG-423?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Alan Gates resolved PIG-423.
----------------------------

    Resolution: Cannot Reproduce

When I run this query now it does not produce the warnings.  If I actually run the script
instead of just describe it, it runs to completion and appears to produce correct results.
 Since it appears the error is somewhat old, I'm assuming some other fix fixed this as well.

> Query:
> grunt> A = load '/user/pig/tests/data/singlefile/studenttab10k' as (name: chararray,
age, gpa);
> grunt> C = foreach A generate (name is null ? '' : (name matches 'foo' ? 'FOO' : name));
> grunt> describe C;
> 08/09/08 16:36:30 WARN pig.PigServer: bytearray is implicitly casted to chararray under
LORegexp Operator
> 08/09/08 16:36:30 WARN pig.PigServer: bytearray is implicitly casted to chararray under
LOBinCond Operator
> C: {chararray}
> The warnings look wrong since name is explicitely declared as chararray.
