   [HIVE-24738](https://issues.apache.org/jira/browse/HIVE-24738) introduced a bug which wont allow generation of insert events when dynamic partition insert is done on existing partitions.
   
   The newFiles list used is null because of the following condition - 
   https://github.com/apache/hive/blob/8077bb118cb418cae24a46f7155c481bf893da99/ql/src/java/org/apache/hadoop/hive/ql/metadata/Hive.java#L3159
   
   The newFiles is assigned to empty list only when new partitions are created and is not assigned when insert is done on existing partitions. This affects insert events generation for external tables.
   
   
   ### Why are the changes needed?
   <!--
   Please clarify why the changes are needed. For instance,
     1. If you propose a new API, clarify the use case for a new API.
     2. If you fix a bug, you can clarify why it is a bug.
   -->
   This is a bug since it does not generate the insert events for existing partitions.
   
   ### Does this PR introduce _any_ user-facing change?
   <!--
   Note that it means *any* user-facing change including all aspects such as the documentation fix.
   If yes, please clarify the previous behavior and the change this PR proposes - provide the console output, description, screenshot and/or a reproducable example to show the behavior difference if possible.
   If possible, please also clarify if this is a user-facing change compared to the released Hive versions or within the unreleased branches such as master.
   If no, write 'No'.
   -->
   No
   
   ### How was this patch tested?
   <!--
   If tests were added, say they were added here. Please make sure to add some test cases that check the changes thoroughly including negative and positive cases if possible.
   If it was tested in a way different from regular unit tests, please clarify how you tested step by step, ideally copy and paste-able, so that other reviewers can test and check, and descendants can verify in the future.
   If tests were not added, please describe why they were not added and/or why it was difficult to add.
