I think the reason here is that

metastore/src/java/org/apache/hadoop/hive/metastore/txn/TxnHandler.java

  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();
...
}

ends up building a query of the form

INSERT INTO TXNS (...) VALUES (...), (...)

Oracle doesn't like this way of inserting multiple rows of data. Couple of ways the following post describe is either inserting each row individually or use the INSERT ALL semantics.
