“readOnly” and other symbols not found when executing shell script remotely

Question

I have a simple shell script below :

#!/bin/bash
# Hadoop Clear
readOnly hadoop = /opt/hadoop/bin/hadoop
hadoop fs -rm -r /

When I run the script in the terminal of the same machine, everything works without error. Now, I want to invoke this script remotely. So from my java program, I do an ssh to the server, and invoke the script as : sh <full Path to script> .

I get an error saying:

clearHadoop.sh: readOnly: not found
clearHadoop.sh: hadoop not found

Any idea why this happens?

Answer 1

readonly is a bash keyword, not readOnly .

This sounds like you are adding the path to hadoop to $PATH in a shell init file that only affects interactive sessions (and so not remote sessions).

Also sh is not /bin/bash . If you want bash use bash and not sh .

Answer 2

There's a typo in your readOnly line. At least the bash's that I just tried al complained about read O nly
