[jira] [Commented] (HIVE-4282) Implement vectorized column-scalar expressions

    [ https://issues.apache.org/jira/browse/HIVE-4282?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13635539#comment-13635539 ] 

Jitendra Nath Pandey commented on HIVE-4282:
--------------------------------------------

A patch is uploaded. All the files in the ql/src/java/org/apache/hadoop/hive/ql/exec/vector/expressions/gen/ directory are files generated from a template.
The template files are in ql/src/java/org/apache/hadoop/hive/ql/exec/vector/expressions/templates/.

The code to generated the files is in CodeGen.java. We plan to add an ant task to generate the files from the templates, which we will do in a follow up jira.
