[jira] [Updated] (HIVE-23798) A rotten comment in VectorizationContext.java

     [ https://issues.apache.org/jira/browse/HIVE-23798?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

ackelcn updated HIVE-23798:
---------------------------
    Description: 
When I read the code of VectorizationContext.java, I found four references to HIVE-7421, and a comment is as follows:

 
{code:java}
private VectorExpression getCastToChar(List<ExprNodeDesc> childExpr, TypeInfo returnType)
      throws HiveException {
    ExprNodeDesc child = childExpr.get(0);
    String inputType = childExpr.get(0).getTypeString();
    if (child instanceof ExprNodeConstantDesc) {
      // Don't do constant folding here.  Wait until the optimizer is changed to do it.
      // Family of related JIRAs: HIVE-7421, HIVE-7422, and HIVE-7424.
      return null;
    }
    ...
}
{code}
 

The comment mentions HIVE-7421. I found that  modified VectorUDFDateString.java, and the patch is as follows:

 
{code:java}
@@ -41,13 +45,10 @@
           return null;
         }
         try {
-          Date date = Date.valueOf(s.toString());
-          t.set(date.toString());
+          Date date = formatter.parse(s.toString());
+          t.set(formatter.format(date));
           return t;
-        } catch (IllegalArgumentException e) {
-          if (LOG.isDebugEnabled()) {
-            LOG.info("VectorUDFDateString passed bad string for Date.valueOf '" + s.toString() + "'");
-          }
+        } catch (ParseException e) {
           return null;
{code}
  

 

The patch modified the evaluate method. However, the method is already deteleted in the latest version.  

 

 I am wondering whether VectorizationContext.java mentions a rotten issue report (), in that all the modifications of this issue do not appear in the latest version.

 

Would you please check the problem? If it is, the reference of  shall be removed from the comment of  VectorizationContext.java.
