This wasn't a problem in 0.9.2, but in 0.10, when I try to access a key in
a map that has a dollar sign in it, I get hammered with errors that I
haven't defined the variable. Specifically:
blah = FOREACH meh GENERATE source, json_post_id#'$id' AS post_id;
Undefined parameter : id
That's fine and makes sense, but when I amend it to:
blah = FOREACH meh GENERATE source, json_post_id#'\$id' AS post_id;
Unexpected character '$'
