Prasanth Jayachandran commented on HIVE-18659: ---------------------------------------------- [~ekoifman] Looks like there are 2 versioning methods now. I am seeing another side file (_orc_acid_version) with version info. Why not use that? Reading version from side file is cheaper (read a single int from side file instead of parsing/reading from footer) isn't it? > add acid version marker to acid files > ------------------------------------- > > Key: HIVE-18659 > URL: https://issues.apache.org/jira/browse/HIVE-18659 > Project: Hive > Issue Type: Bug > Components: Transactions > Reporter: Eugene Koifman > Assignee: Eugene Koifman > Priority: Major > Attachments: HIVE-18659.01.patch > > > add acid version marker to acid files so that we know which version of acid > wrote the file -- This message was sent by Atlassian JIRA (v7.6.3#76005)
