No Files in Local File System and HDFS

After I logged in, I don’t see any files in my local file system and HDFS. Please help me.

Hi Ramesh, did you copy the files from servers local directory? Please copy the files using “hadoop fs -copyFromLocal local_dir hdfs_dir” to view your files.

hadoop fs -copyFromLocal /Users/Rbala22/Desktop/deckofcards.txt ~/demo2/data/cards
copyFromLocal: /home/rajeshwaranb/demo2/data/cards': No such file or directory:hdfs://’
If tried to copy some data from local to HDFS.I got this above error.Please advise what is wrong here
