> The quoted snippet (see below) intends to set HIVE_HOME if it's not set (i.e. HIVE_HOME
is currently null).
> {code}
> if [ -n ${HIVE_HOME} ]; then
> {code}
> However, {{-n}} checks if the variable is _not_ null. So, the above code ends up setting
HIVE_HOME to the default value if it is actually set already, overriding the set value. This
condition needs to be negated.
> Moreover, {{-n}} checks requires the string being tested to be enclosed in quotes.
