ok. so there you go.   IMO, you're going to have to create a custom wrapper around hive so that your users find your wrapper (via PATH) before they find the real hive executable.

Your wrapper checks for whatever you deem acceptable and if so calls the real hive else errors out with your message.

pseudo-code:

#!/bin/bash
if [[ $#-eq 0 ]]; then
      echo "your message"
      exit 1;
else
      exec /path/to/real/hive $@
fi

there are other edge cases you may want to consider.  "hive -service cli" would pass and you wouldn't want that but you get the idea i presume.

Hi
To clarify what I need is as follows

- User types hive
 - Message is displayed "Cannot use hive without -e or -f options"

not sure i understand.  you're asking how to disable  "hive" (with no args)  [interactive mode]  yet still permit "hive -e" [batch mode]?

if that's the case my proposal would be to have a wrapper around the hive executable and check if stdin is a tty.

then again if i've completely misunderstood the question could you elaborate?

Hi
I want to disable Hive CLI interactive mode for Hive clients in production accessing Hive. Mainly due to the following error…This error is solved in future 0.10.0+ versions perhaps but unfortunately upgrading is Not an option today since we are moving to production in the next few hours !!! YEAH…First Hive deployment in production…Thanks guys for that Hive Book and thanks all for your wonderful discussions and answers !

The second big project I am wrapping up is is moving to production on June 1st

Thanks
