[HIVE-9818] Print error messages on stderr instead of stdout

• Type: Bug

Description

hcat script (see here, for example) prints error messages via echo which go on stdout the way they are written. This is bad because downstream projects using it receive error messages as expected output instead of actually receiving nothing (see SQOOP-2147 as example).

We need to put error messages on stdout. Something like:

>&2 echo "This is an error message"

instead of a simple echo that we have been using so far.
