Frédéric ESCANDELL commented on HIVE-15970: ------------------------------------------- Hi, When I exécute the following Hive request, i have an issue : DELETE FROM braff.controle WHERE id_prestation IN ( SELECT distinct id_prestation FROM bbrut.controle_vue WHERE yearbrut='0000'); FAILED: IllegalStateException Expected 'insert into table braff.controle select ROW__ID from braff.controle sort by ROW__ID' to be in sub-query or set operation. I don't understand this exception which has been added to correct this ticket ? > Fix merge to work in presence of AST rewrites > --------------------------------------------- > > Key: HIVE-15970 > URL: https://issues.apache.org/jira/browse/HIVE-15970 > Project: Hive > Issue Type: Sub-task > Components: Transactions > Affects Versions: 2.2.0 > Reporter: Eugene Koifman > Assignee: Eugene Koifman > Priority: Critical > Fix For: 2.2.0 > > Attachments: HIVE-15970.01.patch, HIVE-15970.02.patch > > > The issue is that Context.getDestNamePrefix() caches ASTNode objects to > figure out if a given insert branch of multi-insert is insert, update or > delete but objects change when the tree is modified. For example, > row-filtering/column-masking does this, but also other optimizations/features. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
