如何将python元组（内部列表）传输到HDFS Directry。 （不创建文件）

Question

在此代码中，

DELETE FROM TBL1  WHERE ID  IN
(SELECT ID FROM TBL1  a WHERE ID!=
(select MAX(ID) from TBL1  where DUPVAL=a.DUPVAL 
group by DUPVAL
having count(DUPVAL)>1))

def run_cmd(args_list):
        # import subprocess
        print('Running system command: {0}'.format(' '.join(args_list)))
        proc = subprocess.Popen(args_list, stdout=subprocess.PIPE, stderr=subprocess.PIPE)
        s_output, s_err = proc.communicate()
        s_return =  proc.returncode
        return s_return, s_output, s_err 

如何在不编写文件的情况下将“ local_file”替换为python变量（列表中的字符串或元组）？
