Jason Dere commented on HIVE-17645:
-----------------------------------
[~sershe] brought this to my attention as well, plus the fact that the
sessionstate txn manager is being called in some of the semantic analyzer code:
- SemanticAnalyzer.genFileSinkPlan()
- ReplicationSemanticAnalyzer.analyzeReplLoad()
- LoadSemanticAnalyzer.analyzeExternal()
- ImportSemanticAnalyzer.prepareImport()
- DDLSemanticAnalyzer.handleTransactionalTable()
As Sergey mentions earlier, most of these (with the exception of
genFileSinkPlan) are probably ok since they are related t DDL/import/repl,
which would not happen for HIVE-17482. But probably good to fix these so that
all examples of getting the txn manager use the same call.

> Key: HIVE-17645
> URL: https://issues.apache.org/jira/browse/HIVE-17645
> Project: Hive
> Issue Type: Sub-task
> Components: Transactions
> Affects Versions: 3.0.0
> Reporter: Eugene Koifman
> Assignee: Eugene Koifman
> Priority: Major
> Labels: mm-gap-2
>
> MM code introduces
> {noformat}
> HiveTxnManager txnManager = SessionState.get().getTxnMgr()
> {noformat}
> in a number of places (e.g _DDLTask.generateAddMmTasks(Table tbl)_).
> HIVE-17482 adds a mode where a TransactionManager not associated with the
> session should be used. This will need to be addressed.
