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.
