我想提供一个hiveclient.jar来执行配置单元sql。代码如下

public class HiveClient {
    private String sql;

    public HiveClient(String sql) {
        this.sql = sql; 
    }

    public int procedure(){
        String[] command = {"hive", "-e", sql};
        Process process = Runtime.getRuntime().exec(command);
        ...
        do something with process...
    }

}
我将输入sql并从process.getinputstream（）获取输出。
问题是，当我在linux shell中调用这个jar时，一切正常

java -cp .:./hiveClient.jar HiveMain

但是当我把这个jar放在tomcat lib文件夹中，并调用这个对象时，会出现permission deny错误。但是，hive用户和tomcat用户都是“admin”。

HiveClient hc = new HiveClient(parameters.toString());
int returnCode = hc.procedure();

我想知道我怎么能在tomcat里叫“Hive-e”，非常想你！
