I think the reason here is that
{code:title=metastore/src/java/org/apache/hadoop/hive/metastore/txn/TxnHandler.java|borderStyle=solid}
public OpenTxnsResponse openTxns(OpenTxnRequest rqst) throws MetaException {
...
String query;
String insertClause = "insert into TXNS (txn_id, txn_state,
txn_started, txn_last_heartbeat, txn_user, txn_host) values ";
StringBuilder valuesClause = new StringBuilder();
for (long i = first; i < first + numTxns; i++) {
txnIds.add(i);
if (i > first &&
(i - first) %
conf.getIntVar(HiveConf.ConfVars.METASTORE_DIRECT_SQL_MAX_ELEMENTS_VALUES_CLAUSE)
== 0) {
// wrap up the current query, and start a new one
query = insertClause + valuesClause.toString();
queries.add(query);
valuesClause.setLength(0);
valuesClause.append("(").append(i).append(", 'o',
").append(now).append(", ").append(now)
.append(", '").append(rqst.getUser()).append("',
'").append(rqst.getHostname())
.append("')");
continue;
}
if (i > first) {
valuesClause.append(", ");
}
valuesClause.append("(").append(i).append(", 'o',
").append(now).append(", ").append(now)
.append(", '").append(rqst.getUser()).append("',
'").append(rqst.getHostname())
.append("')");
}
query = insertClause + valuesClause.toString();
...
}
{code}
ends up building a query of the form
{code:sql}
INSERT INTO TXNS (...) VALUES (...), (...)
{code}
Oracle doesn't like this way of inserting multiple rows of data. Couple of ways
the following [post|http://www.oratable.com/oracle-insert-all/] describe is
either inserting each row individually or use the {{INSERT ALL}} semantics.
