  • Provided link is broken. Nice example why it is recommended to post at least a tl;dr version of the link. – Dror Jul 14 '15 at 15:19

    This is the same link as in the answer, but linked to "current" instead of a specific version "r2.7.0": http://hadoop.apache.org/docs/current/hadoop-project-dist/hadoop-common/FileSystemShell.html – michael Aug 20 '16 at 12:53

To copy from local to hdfs, use this command:

hadoop fs -copyFromLocal /temporaryfile.txt hdfs://DFCMSUSEHDSL03.pbi.global.pvt/sunil/temporaryfile.txt

OR

hadoop fs -copyFromLocal /temporaryfile.txt hdfs://DFCMSUSEHDSL03.pbi.global.pvt:8020/sunil/temporaryfile.txt

OR 

hadoop fs -put /temporaryfile.txt /sunil/temporaryfile.txt
