Wei Zheng commented on HIVE-11716: ---------------------------------- Sounds good. Now users can change the TxnManager for real. But one issue is, initialize a TxnManager for every query might be a little slower than reusing the same one in a session (because we will check conf every time and init a TxnManager) > 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)
