Question

我需要从sqoop hsql数据库检索有关sqoop作业的数据。所以我下载了最新版本的hsqldb连接器，然后连接到sqoop数据库，如：

public void extract() {
        try {
            conn = DriverManager.getConnection(connectionString, username, password);
            conn.setTransactionIsolation(2);
            conn.setAutoCommit(false);


           //.....
        } catch (SQLException e) {
           //...
        }
    }

与本地sqoop hsqldb的连接已成功，但是它重写了metastore.db.properties和metastore.db.script。

因此，在此连接之后，无论何时sqoop尝试连接到本地数据库，都会给我错误。例如，当我要列出带有sqoop之类的作业时：sqoop job --list时，会出现此异常：

有人能告诉我如何在不重写那些文件的情况下连接到sqoop本地hsqldb吗？
