Answer 1

You can use hadoop fs -ls command to list files in the current directory as well as their details. The 5th column in the command output contains file size in bytes.

For e.g. command hadoop fs -ls input gives following output:

Found 1 items
-rw-r--r--   1 hduser supergroup      45956 2012-07-19 20:57 /user/hduser/input/sou

The size of file sou is 45956 bytes.
