Eugene Koifman commented on HIVE-18774: --------------------------------------- suppose you have 2 Load Data statements in 1 txn 1st one creates delta_7_7_0/ with 0000_0 and 0000_0_copy_1 2nd one creates delta_7_7_1/ with 0000_0 and 0000_0_copy_1 so you can't simply take N from copy_N and use it as stmt id > ACID: Use the _copy_N files copyNumber as the implicit statement-id > ------------------------------------------------------------------- > > Key: HIVE-18774 > URL: https://issues.apache.org/jira/browse/HIVE-18774 > Project: Hive > Issue Type: Bug > Components: Transactions > Environment: if this is not done in 3.0 it cannot be done at all > Reporter: Gopal V > Assignee: Eugene Koifman > Priority: Blocker > > When upgrading flat ORC files to ACID, use the _copy_N numbering as a > statement-id to avoid having to align the row numbering between _copy_1 and > _copy_2 files. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
