Subject [jira] Commented: (PIG-1563) SUBSTRING function is broken
Date Sat, 28 Aug 2010 01:25:54 GMT

    [ https://issues.apache.org/jira/browse/PIG-1563?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12903753#action_12903753
] 

Dmitriy V. Ryaboy commented on PIG-1563:
----------------------------------------

+1

question/comment -- any reason you discarded the new buildSimpleFuncSpec I wrote in the first
iteration of this patch? I think it simplifies the code:

{code}
funcList.add(Utils.buildSimpleFuncSpec(
  this.getClass().getName(), DataType.CHARARRAY, DataType.CHARARRAY));
{code}

vs
{code}
Schema s = new Schema();
s.add(new Schema.FieldSchema(null, DataType.CHARARRAY));
s.add(new Schema.FieldSchema(null, DataType.CHARARRAY));
funcList.add(new FuncSpec(this.getClass().getName(), s));
{code}
