[jira] [Updated] (HIVE-17284) remove OrcRecordUpdater.deleteEventIndexBuilder

["Eugene Koifman (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/HIVE-17284?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Eugene Koifman updated HIVE-17284:
----------------------------------
    Description: 
There is no point in it. We know how many rows a delete_delta file has from ORC and they are all the same type - so no need for AcidStats.
 hive.acid.key.index has no value since delete_delta files are never split and are not likely to have more than 1 stripe since they are very small.

Also can remove KeyIndexBuilder.acidStats - we only have 1 type of event per file

 

if doing this, make sure to fix {{OrcInputFormat.isOriginal(Reader)}} and {{OrcInputFormat.isOriginal(Footer)}} etc
