Eugene Koifman commented on HIVE-11716: --------------------------------------- I think you need to use AcidUtil.isTablePropertyTransactional() to see if table is transactional rather than AcidUtils.isAcidTable(tab). The later will return false for table that was non-acid-to-acid upgraded but w/o major compaction having been run. Maybe even better to define a new isAcidTable(Table t) method which checks that it's bucketed, implements AcidInput/AcidOutputFormat and has the transactional=true. Also, SemanticAnalyzer.isAcidTable() should delegate to new method (or be removed) or at minimum not check the which TxnManager is installed > Reading ACID table from non-acid session should raise an error > -------------------------------------------------------------- > > Key: HIVE-11716 > URL: https://issues.apache.org/jira/browse/HIVE-11716 > Project: Hive > Issue Type: Bug > Components: Transactions > Affects Versions: 1.0.0 > Reporter: Eugene Koifman > Assignee: Wei Zheng > Priority: Critical > Attachments: HIVE-11716.1.patch, HIVE-11716.2.patch > > > if someone performs a delete using DbTxnManager and than starts a new session > with DummyTxnManager, then previously successfully deleted data will show up. > Once the logic to identify all acid tables being read is there, make sure that > Driver.recordValidTxns() called iff there ACID tables in the query. > We should also not allow writing to ACID table from non-acid session -- This message was sent by Atlassian JIRA (v6.3.4#6332)
