-------------------------------------
Summary: Hive Statement Does Not Clear Statement Handle on Error
Key: HIVE-23601
URL: https://issues.apache.org/jira/browse/HIVE-23601
Project: Hive
Issue Type: Bug
Reporter: David Mollitor
Assignee: David Mollitor
{code:java}
private void closeStatementIfNeeded() throws SQLException {
try {
if (stmtHandle != null) {
TCloseOperationReq closeReq = new TCloseOperationReq(stmtHandle);
TCloseOperationResp closeResp = client.CloseOperation(closeReq);
Utils.verifySuccessWithInfo(closeResp.getStatus());
stmtHandle = null;
}
} catch (SQLException e) {
throw e;
} catch (Exception e) {
throw new SQLException("Failed to close statement", "08S01", e);
}
}
void closeClientOperation() throws SQLException {
closeStatementIfNeeded();
isQueryClosed = true;
stmtHandle = null;
}
{code}
{{verifySuccessWithInfo}} throws an {{Exception}} if it finds an error code and
therefore leapfrogs over setting the statement handle to null (twice).
Probably not what is intended since the original author(s) are tried twice to
null it out.
