about hadoop fs test command output

Question

I am running below command, tried to use either filename exists, or filename not exists, but none of them have any outputs from console. I expect if a file exists, the command should return zero?

http://hadoop.apache.org/docs/current/hadoop-project-dist/hadoop-common/FileSystemShell.html#test

hadoop fs -test -e filename

Answer 1

I think it means the return code of the command is 0.

You can check with

hadoop fs -test -e filename
echo $?

Answer 2

Try

hadoop fs -test -d <HDFSFilename>

You should see test: File does not exists

If the file does not exists - and a blank string if it does

1=$(hadoop fs test -d <HDFSFilename>)

I am sure you are using a HDFS filename and not a Linux based filename - but best check

hadoop fs -ls /
