hadoop webhdfs创建。我不能传送文件

我无法将文件传输到Hadoop。下面我添加了我使用过的命令和获得的错误

命令1：

curl -i -X PUT "http://myip:50070/webhdfs/v1/tmp/tempForTest.txt?user.name=hadoop&op=CREATE&overwrite=false&createparent=false&replication=1&permission=777"

请参见

curl-i-X PUT-T

---

您缺少一个

-T

，并且它将您的文件作为URL，格式不正确，因此错误

基本上不确定您为什么要重新提交上一个问题

curl -i -X PUT -T <LOCAL_FILE>
