[jira] [Created] (HIVE-23471) Statement.executeUpdate() does not
return correct affected records causing "No such lock"
Riju Trivedi created HIVE-23471:
-----------------------------------
Summary: Statement.executeUpdate() does not return correct affected records causing "No such lock"
Key: HIVE-23471
URL: https://issues.apache.org/jira/browse/HIVE-23471
Project: Hive
Issue Type: Bug
Components: Hive
Affects Versions: 3.1.0
Reporter: Riju Trivedi
Assignee: Denys Kuzmenko
In TxnHandler.acquire() call , Statement.executeUpdate() does not return correct number of records updated in HIVE_LOCKS table as requested number of locks.
This results in error "*Couldn't find a lock we just created! No such lock(s)*" as acquire is rolled back.
{code:java}
int rc = stmt.executeUpdate(s);
if (rc < locksBeingChecked.size()) {
LOG.debug("Going to rollback acquire(Connection dbConn, Statement stmt, List<LockInfo> locksBeingChecked)");
dbConn.rollback();
/*select all locks for this ext ID and see which ones are missing*/
StringBuilder sb = new StringBuilder("No such lock(s): (" + JavaUtils.lockIdToString(extLockId) + ":");
{code}
