Report the command that is failing

Created by: muffato

Use case

Since 2.5, the commands being run are by default hidden (they can be shown with the -hive_debug_init 1 flag), so if something goes wrong, you can only see the error message, not the command that caused the error.

Description

When the command fails, print it too, alongside the error message.
