hadoop fs -put command
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 local hdfs user has read rights before trying to copy it to HDFS.
Try:
cp /root/MyHadoop/file1.txt /tmpchown hdfs:hdfs /tmp/file1.txt# older versions of Hadoopsudo -u hdfs hadoop fs -put /tmp/file1.txt /# newer versions of Hadoopsudo -u hdfs hdfs dfs -put /tmp/file1.txt /--- edit:
Take a look at the cleaner roman-nikitchenko's answer bellow.
I had the same situation and here is my solution:
HADOOP_USER_NAME=hdfs hdfs fs -put /root/MyHadoop/file1.txt /Advantages:
- You don't need
sudo. - You don't need actually appropriate local user 'hdfs' at all.
- You don't need to copy anything or change permissions because of previous points.
