I'm fine with the variable placeholder not being removed in cases where the
variable is not defined (until I change my mind). When I define var2 and var3,
though, their placeholders aren't swapped for their values.
My reasoning for this was that I'm moving from one execution script that
defines
It was done like this in hive because that is what hadoops variable
substitution does, namely if it does not understand the variable it does
not replace it.

Even newer versions of Hive do this. Any reason you don't want to provide a
definition for all of them? You could argue that an undefined variable is a
bug and leaving the literal text in place makes it easier to notice.
Although, Unix shells would insert an empty string, so never mind ;)
On Wed,
I'm using Hive 0.7.0. Yeah, this is out of my expectation.

No. Variable substitution works for anything. Likely your version of hive
is old and does not support this at all.

Yeah, you're not the only one who's run into that issue. There is an open Jira
item for it, so they're aware we'd like it configurable anyway...

Unfortunately you are going to have to roll your own hive. It was just
a concept we borrowed from Hadoop since it does not support more then
40 depth substitution. We can probably make
