Python FileNotFoundException:File File:/path/to/File/in.txt不存在，或者运行Flink的用户没有足够的权限访问它

我正在尝试使用flink和python批处理api测试Wordcount经典示例。 我的问题是，在将数据源从env.from_elements（）修改为env.read_text（）后（对于更大的测试用例），会发生错误。下面的代码描述了我的实现

[...]
if __name__ == "__main__":
env = get_environment()
input_file = 'file:///workfile.txt/'

if len(sys.argv) != 1 and len(sys.argv) != 3:
    sys.exit("Usage: ./bin/pyflink.sh WordCount[ - <text path> <result path>]")

if len(sys.argv) == 3:
    data = env.read_text(sys.argv[1])
else:
    #data = env.from_elements("hello","world","hello","car","tree","data","hello","car","tree","data","hello","car","tree","data","hello","car","tree","data","hello","car","tree","data","hello","car","tree","data","hello","car","tree","data","hello","car","tree","data","hello","car","tree","data","hello","car","tree","data","hello","car","tree","data","hello","car","tree","data","hello","car","tree","data","hello","car","tree","data","hello","car","tree","data","hello","car","tree","data","hello","car","tree","data","hello","car","tree","data","hello","car","tree","data","hello","car","tree","data","hello","car","tree","data","hello","car","tree","data","hello","car","tree","data","hello","car","tree","data","hello","car","tree","data","hello","car","tree","data","hello","car","tree","data","hello","car","tree","data","hello","car","tree","data","hello","car","tree","data","hello")
    data = env.read_text(input_file)

result = data \
    .flat_map(Tokenizer()) \
    .group_by(1) \
    .reduce_group(Adder(), combinable=True) \

if len(sys.argv) == 3:
    result.write_csv(sys.argv[2])
else:
    result.output()
[...]

如果名称=“\uuuuu main\uuuuuuuu”：

如果len（sys.argv）！=1和len（系统argv）！=三：

如果len（sys.argv）==3：
数据=环境读取文本（sys.argv[1]）
其他：

执行上述代码时，会抛出一个文件权限错误。更具体地说，以下消息

原因：org.apache.flink.runtime.JobException:创建输入拆分导致错误：File File:/workfile.txt不存在，或者运行flink的用户（“用户”）没有足够的权限访问它

PS：已搜索解决方案，但找不到任何内容。如果这个问题已经解决，我将非常感谢重定向。

我假设“workfile.txt”应该是一个相对路径。但是，您不能有带有方案的相对文件（“文件：//”）

请提供完整的绝对路径，它应该可以工作

---

请注意，相对路径通常不适用于Python API，因为我们在临时位置执行脚本。

能否共享您的

get\u环境

？环境不包含任何信息，它只是一个API。感谢您的评论eah，绝对路径就是解决方案。但出于某种原因，我认为绝对路径就是我称之为flink的工作经理的路径。然后我尝试了从/home/to/flink/txt/path的路径，结果很好。
