我正试图用下面提到的代码通过python脚本向hdfs编写一个文件。
import hadoopy
import os
hdfs_path = 'data.json'
def read_local_dir(local_path):
for fn in os.listdir(local_path):
path = os.path.join(local_path, fn)
if os.path.isfile(path):
yield path, open(path).read()
def main():
local_path = '.'
hadoopy.writetb(hdfs_path, read_local_dir(local_path))
if __name__ == '__main__':
main()
在本例中,要执行上面的代码 pip install hadoopy
包,但安装失败。还尝试了下载hadoopy-0.5.0.tar.gz进行安装,但没有成功。请帮我解决这个问题。
错误:
> pip install hadoopy
