解决方案 / （在你的本地硬盘）？通常你不会。您必须将 file1.txt 复制到 hdfs 用户具有读取权限的地方。

Try：

cp /root/MyHadoop/file1.txt / tmp chown hdfs：hdfs /tmp/file1.txt sudo -u hdfs hadoop fs -put /tmp/file1.txt /

请看更清洁的罗马尼基琴科的回答。

I have constructed a single-node Hadoop environment on CentOS using the Cloudera CDH repository. When I want to copy a local file to HDFS, I used the command:

sudo -u hdfs hadoop fs -put /root/MyHadoop/file1.txt /

But,the result depressed me:

put: '/root/MyHadoop/file1.txt': No such file or directory

I'm sure this file does exist.

Please help me,Thanks!

解决方案

As user hdfs, do you have access rights to /root/ (in your local hdd)?. Usually you don't. You must copy file1.txt to a place where hdfs user has read rights.

Try:

cp /root/MyHadoop/file1.txt /tmp chown hdfs:hdfs /tmp/file1.txt sudo -u hdfs hadoop fs -put /tmp/file1.txt /
