----------------------------------
Summary: TxnDbUtil should turn off jdbc auto commit
Key: HIVE-11939
URL: https://issues.apache.org/jira/browse/HIVE-11939
Project: Hive
Issue Type: Bug
Reporter: Jimmy Xiang
Assignee: Jimmy Xiang
Priority: Minor
TxnDbUtil uses jdbc transactions, but doesn't turn off auto commit. So some
TestStreaming tests are flaky. For example,
{noformat}
testTransactionBatchAbortAndCommit(org.apache.hive.hcatalog.streaming.TestStreaming)
Time elapsed: 0.011 sec <<< ERROR!
java.sql.SQLException: Table/View 'TXNS' already exists in Schema 'APP'.
