Python “操作员抛出”；没有这样的文件或目录；错误

我无法找出我提出的问题，日志如下所示。 下面还显示了我创建的DAG、connection和pig脚本

达格：

猪字：

rmf /onlyvinish/sample_out;
a_load = load '/onlyvinish/sample.txt' using PigStorage(',');
a_gen = foreach a_load generate (int)$0 as a;
b_gen = foreach a_gen generate a, a+1, a+2, a+3, a+4, a+5;
store b_gen into '/onlyvinish/sample_out' using PigStorage(',');

不在您的路径中。如果是这样，pig内容在日志中的显示方式@Jean François Fabrecan你能详细说明一下吗？
