   There is a utility in hive which can validate/fix corrupted hive.acid.key.index: `hive --service fixacidkeyindex`.
   
   The utility throws a NPE if the hive.acid.key.index metadata entry is missing, the patch allows to keep processing the ORC file and insert the missing hive.acid.key.index metadata.
   
   ### 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.
   -->
   
   ORC acid files can be legally missing this property, so handling such cases is needed.
   
   ### 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.
   -->
   
   Added a test covering the case in `TestFixAcidKeyIndex`:
   ```
   mvn test -Dtest=TestFixAcidKeyIndex -pl ql
   ```
